Five New Machin Priority Service Stamps - 28 February 1995

In February 2009 Royal Mail issued the first self-adhesive definitive NVIs and high values stamps with new security features.  This was the birth of the Machin Security Stamps which indirectly lead to the bulk of posts on this blog over the next decade.

Then in November two surprise additions to the series were added, the Recorded Signed For 1st class and 1st class Large to “satisfy an operational demand at Post Office counters”.

As we know these were self-adhesive, die cut, with security features, with slits through the stamp and with iridescent printing across the design.   The slits were said to be designed to inhibit the removal of these Stamps for fraudulent sale and re-use.

But although this was described as an innovation it wasn't actually new – the concept originated in 1994, as shown in an internal Royal Mail document found by one of our contributors MM.

This document shows that Royal Mail were considering special stamps for Priority Servics with what would seem to be the very same security features.

“The stamps will be self-adhesive and die-cut, 25 to a sheet, with additional security features because of he stamp's premium.”

Design: a centrally-placed embossed Machin head (29.5 mm), with the service indicator at the bottom of the stamp which would be of similar colour and branding to the specific services. Unfortunately there are no pictures (in any case it is a black and white potocopy) and we don't know what colours they were planning. I suspect predominently dark blue iwith different inscriptions, per this leaflet.

(More on the new labelling and system below.) 

The costs of the service, and therefore of the stamps, is shown as follows.

Recorded Delivery - 55p

Special Delivery - £2.70

Registered - £3.00

Registered Plus to £1500 - £3.30

Registered Plus to £2200 - £3.60

Note that these are supplementary stamps – in addiition to 1st class postage (or a choice of 2nd or 1st for Recorded Delivery) for the weight concerned.

The issue date was to be 28 February 1995 with stamp cards (PHQ cards), presentation packs, and “philatelic souvenir covers”, which is an odd way of saying First Day Covers. 

The alternative postmark was Windsor (with the primary one obviously being Philatelic Bureau Edinburgh).

No printer was identified at this stage.

So what happened? Why did this apparently good idea, suggested with the new 1993 branding, fail to be implemented?

Was it problems with Post Office counters, with users, with separation of the different classes in the mail stream?

Maybe someone decided that using an extra stamp for the priority service would be a problem, although it could reduce the number of stamps required. (Stamp dealers of course would have plenty of other value postage to use!)

One thing I do know – if these had been introduced in 1994 as planned, I would not have been as involved in Machin Security Stamps as I came to be in 2009/10 etc. At that time I had not retired, and my interest in Machins was far reduced from its previous peak, and my focus switched to the stamps and postal history of the countries of the Former Soviet Union.

On the other hand, I would have been able to put more focus onto the aforementioned, and Great Britain modern postal history and usages, and I might not have as many boxes to go through now.

 

More on Priority Services.

When introduced in 1961 Recorded Delivery used yellow labels which over the years varied to several different shades of orange. Registered Mail, of course, had used numbered blue 'R” labels for over a century, and Special Delivery was identified by a white on green label for many decades.

The June 1993 leaflet 'Now Even Better” illustrated the labels for the new services (shown above), which used dark blue in all cases, which I thought could lead to confusion compared with the previous system. Although the labels stuck on envelopes and packets had different text, further confusion was possible for users as the Registered and Special Delivery (SD) forms were both headed Guaranteed Delivery. In fact it really made no difference to processing as both Guaranteed Delivery services provided the same service, the only difference being that SD paid up to £24 compensation, and Registered paid up to £500.




Recorded retained an orange aspect, Registered had a light blue background to the number labels, and SD had an orange background to the number labels.  Soon afterwards pre-paid postal stationery envelopes were introduced.

From the top, Registered Plus, indicated by the pale blue + at the foot, Registered, and Special Delivery which is lighter blue.

 Here's an example from March 1994.



It's impossible to know, apart from by the postage paid, which service is being used (and not necessarily then!).  In this case postage is £3.08 which is 38p first class postage for a 40-100 g first class letter plus £2.70 Special Delivery fee. 

For the delivery postman it is clear that this is a priority item, but for tracking at any stage from the post office counter to delivery the barcode on the reverse has to be scanned.  Did posties carry any barcode readers then?  

By 1995 a further rebranding introduced the Silver Service for inland Special Delivery and from from 12th October 1998 they were all combined into a single rebranded service under the Special Delivery banner.  (GB Philatelic Society)

This is an interesting and relatively short-lived period in British Postal History affecting more expensive mail than just ordinary letters.  Material is not easy to find, but stamp dealers were always big users of premium services and their covers are more likely to be kept.

I've got more like the one above, but not many.  This will be the subject of a post on the Modern Postal History blog some time.

Has anyone seen a new NHS barcoded letter yet?

In the wake of further criticism on delays to ordinary mail Royal Mail announced in April a new solution for the more important letters from the National Health Service

The solution design provides an option for NHS providers to add a unique NHS identifier into the Mailmark barcode. Where our internal reporting shows that we are not meeting expected quality of service standards regularly, at either a local or a national level, the new NHS barcode will allow us to identify NHS mail and automate its extraction from Royal Mail sorting machines. Thereafter we will discretely handle the mail through to delivery. This will ensure NHS providers get the service they require, and patients receive their letters in a timely manner.

Customers choosing to use the NHS class identifier will need to add it to the class field in the Mailmark barcode and eManifest. This is not a new or separate service. Instead, the NHS barcode would be eligible to be printed on NHS letters using Access Priority (D+2) or Standard (D+3) Mailmark Business Mail services. The option is suitable for patient communications including appointment letters and test results.

I haven't seen any such letters yet, or had any reported, but it is now apparent that these will be handled in the same way as Special Delivery mail, according to this graphic from the Royal Mail website.

Note the original meaning of discreet - "Discrete means separate or divided. A discrete unit is a separate part of something larger."

Postage Value of Older Stamps including Post and Go - October 2025 version.

This post brings previous tables up to date with the postage rates effective from 6 October 2025.

The tables are included primarily to explain the stamps used on cover, because they show that, for example, a stamp originally issued as a 30p Europe 20g stamp would later be valid for 100g and with a value of £1 in 2015 and £2.20 in 2023!

Remember that the International Rate stamps were all valid at the rates shown for inland postage, just as the 2nd, 1st, Large, Signed For, and Special Delivery stamps were all valid for inland services in addition to those shown and on international mail.

Now, of course, the old Machin and Country definitives without barcodes are no longer valid but the Post and Go stamps are as are the commemorative stamps, so the tables are still relevant for new use as well as for for Postal History purposes.

The E stamp was issued from January 1999-2004, and paid the Europe 20g rate.  This was 30p when issued and the cost but also the franking value increased periodically:

October 1999 (34p), April 2000 (36p), July 2001 (37p), May 2003 (38p), April 2004 (40p), April 2005 (42p), April 2006 (44p), April 2007 (48p).

Postal rates 7 April 2025 - basic airmail rate and 1st Large Letter see biggest increases.

By now many of you will have seen news of Royal Mail's next price increases on stamp/Postcrossing forums or social media, but as yet there is no press release so we don't know what weasley words Royal Mail will use this time to justify some quite large rises.

Press Release added 2106 7 March:

Royal Mail carefully considers prices, balancing affordability with the increasing cost of delivering mail. 

Letter volumes have fallen from 20 billion a year in 2004/5 to 6.7 billion in 2023/4, and could fall to 4
billion a year within the next four years. Over the same period, the number of addresses has risen by four million meaning the cost of each delivery continues to rise.

Nick Landon, Chief Commercial Officer at Royal Mail said: “We always consider price changes very
carefully but the cost of delivering mail continues to increase. A complex and extensive network of trucks, planes and 85,000 posties are needed to ensure we can deliver across the country for just 87p.

“Ofcom has recognised that reform is urgently needed to protect the one-price-goes-anywhere Universal
Service which requires Royal Mail to deliver letters to around 32 million UK addresses six days a week.
Reform will allow continued investment in the modernisation and transformation of the business to
provide a more financially sustainable service.” 

Ends

======================================

The new rate chart can be downloaded here.  New prices in bold, unchanged rates in italics, reduced price in red.  The differential between 2nd and 1st for a 100g Large Letter rises from £1.05 to £1.60 (and 12 months ago it was only 55p!). 

The 2nd class rate for 100-250g is reduced to below the April 2024 rate and is now only 15p more than the April 2023 rate, presumably reflecting market forces.  If it doesn't matter that 2nd class will only be delivered on alternate days this seems to be a much better option than 1st class.

Special Delivery rates are also increased.  The 100g rate rises by 40p from £8.35 to £8.75, the 500g rate by 50p to £9.85. Increases for delivery by 9am are between 11% and 21%.

UK Tracked rates see minor increases.  The basic 1st class Large Letter rate is again raised by 10p to £3.70, the Small Parcel rate by 16p to £5.15.  The 2nd class rate remains at £2.80 for 750g the Small Parcel is up by 10p to £4.05. 

UK Signed is up from £3.35 to £3.60 1st class and from £2.55 to £2.77 for 2nd class.

International rates.   The basic letter rates are increased, but not the Large Letter and Parcel rates.  The airmail rate which increased in October from £2.50 to £2.80 goes up a further 40p to £3.20, and the surface rate is up 50p to £3.10.  This is bad news for PostcrossersIt will bring a new barcoded definitive of £3.20; however creating either rate from special stamp issues is going to be more difficult especially with the size of new barcoded stamps to make up any shortfall.

A quick look at Premium services - International Tracked, Signed, and Tracked & Signed see changes of up to 15% but not at all levels.

The stamps

Prices for Large Letter Airmail stamps have remained static since January 2021, so it should be no surprise that they are now higher and will require new stamps.

Airmail rate stamps issued 27 March 2025: £3.20 spruce green (100g letter rate)
£3.50 Wood Brown (100g Large Letter Europe)
£4.20 Bright Blue (100g Large Letter Worldwide).


Technical details are the same as for other definitive stamps: printed in gravure on self-adhesive sheets of 25 by Cartor Security Printers.  The security codes are MAIL M25L.  The printing dates are 13, 14 & 15th January 2025 respectively (lowest to highest).

This post is now open for comments - and corrections.


Tuesday, 2 July 2024

You can use stamps for posting Special Delivery and other premium mail.

You knew that, of course?  We all do - we've been using the postal service for up to 60 years and we know what's what, more or less - until the rules change.

So why raise the point?  Well the problem lies mainly with Business users, but I can see that the misinformation currently being spread by Royal Mail could also start coming from Post Office especially as more and more new people are employed in customer-facing positions.


Just as an aside on this last point, after the stamp alongside was withdrawn from sale in mid-2021, I took some mail to a sub-PO counter in a local Co-op corner shop.  

It weighed more than 100g, so I used one of these stamps and others. The person who served me didn't recognise it, didn't know how much it was worth, so didn't know whether the item was fully paid, and declined to accept it.  I had to take it to the local Crown Office where no such problems exist.

Anyway, I digress.  This (below in red) is what a business user was told by Royal Mail Business Customer Service when he tried to claim on a delayed Special Delivery packet:

that Postage Stamps would not be valid for paying the fee and that the use of barcodes (which we have on rolls of 250/500) could not be used.

That this was being phased out and that customers were advised last January. People using these barcodes and postage stamps as payment would have the item Surcharged.

She said that you have 3 ways to get a Barcode and have it paid for.

1) Online and Pay by credit card

2) Take it to the Post Office and get a computer generated Barcode.

3) Use a Franking Machine

 

Like I said above, misinformation - in the extreme.  So I also phoned Royal Mail Business Customer Service and had a very interesting discussion. 

Being an ex-civil servant and knowing the way bureaucracies work, I declined to accept what I was told (which was much the same).  I pointed out that until recently Royal Mail actually issued stamps which had a Special Delivery inscription for two weights.

I politely suggested that the Customer Service Assistant went and asked someone who had worked in Royal Mail for a long time, as I had - just the previous week - sent some invalidated stamps to the Swapout scheme, using stamps to pay for Special Delivery, and another by International Tracked to Canada.

(It would be nice if Royal Mail changed their 'hold' music from a short loop.  (When I called my car insurance company this week I was treated to a long play list of Beatles hits!)  It doesn't take long for it to become tedious.)

Eventually the point was conceded, but I was reminded that the items must be posted at a Post Office counter, not in a street box.  I should have held back, but replied that, "yes, that is the way that it has been since registration was introduced in the 19th century".   

I have now got written (email) confirmation of the point - although this really only addresses people posting at Post Office, but not businesses who have their mail collected.  I hope to get clarification on that soon.


UPDATE 31 July:  As this question was originally raised on behalf of business account users who often have their mail collected - who had been told that they would not be able to use stamps - I pushed the question again for business collections, and received this answer.

So provided businesses can get the silver or orange (or international) labels - which they cannot order from Royal Mail - they can carry on as normal.

Postage Value of Older Stamps including Post and Go - 2024 version.

This post brings previous tables up to date with the postage rates effective from 2 April 2024.

The tables are included primarily to explain the stamps used on cover, because they show that, for example, a stamp originally issued as a 30p Europe 20g stamp would later be valid for 100g and with a value of £1 in 2015 and £2.20 in 2023!

Remember that the International Rate stamps were all valid at the rates shown for inland postage, just as the 2nd, 1st, Large, Signed For, and Special Delivery stamps were all valid for inland services in addition to those shown and on international mail.

Now, of course, the old Machin and Country definitives without barcodes are no longer valid but the Post and Go stamps are as are the commemorative stamps, so the tables are still relevant for new use as well as for for Postal History purposes.

The E stamp was issued from January 1999-2004, and paid the Europe 20g rate.  This was 30p when issued and the cost but also the franking value increased periodically:

October 1999 (34p), April 2000 (36p), July 2001 (37p), May 2003 (38p), April 2004 (40p), April 2005 (42p), April 2006 (44p), April 2007 (48p).

Postage Value of older stamps including Post and Go.

I overlooked updating this information at the start of 2022; the post will later incorporate the 2023 tariff.

The tables are included primarily to explain the stamps used on cover, because they show that, for example, a stamp originally issued as a Europe 20g stamp is now valid for 100g and has a current value of £1.85.  So a letter to Europe much heavier than 20g can now use that stamp - up to 100g.  



Likewise,  Worldwide 40g and 60g stamps are now worth £2.55 and can be used anywhere in the world up to 100g.

‡ I've now added the E stamp, issued from January 1999-2004, which is the equivalent of the Europe 20g rate.  This was 30p when issued and the cost but also the franking value increased periodically:

October 1999 (34p), April 2000 (36p), July 2001 (37p), May 2003 (38p), April 2004 (40p), April 2005 (42p), April 2006 (44p), April 2007 (48p), April 2009 - as below.

 

The Worldwide Postcard stamp (shown) issued in 2004 was originally sold at 43p. The cost and the franking value increased - April 2005 (47p), April 2006 (50p), April 2007 (54p), April 2008 (56p), April 2009 as shown in the Worldwide 10g column below.

* With effect from 1 September 2020 a combined Euro 100g/World 20g Post & Go stamp was issued, priced at £1.70.
§ On the same date the World 100g stamp was replaced by two stamps: World 100g Zone 1-3 is sold for £2.50, and World 100g Zone 2 is £2.55.
 
On 1 January 2021 the pricing for all world zones was standardised, although that for large letters over 100g varied.   The Post and Go range was then consolidated to include airmail Large Letter stamps.


Inland premium services



Note that some of the rates were in effect before the stamps were issued, and some new stamps were issued at old rates before tariff increases.

* Royal Mail Signed For stamps were issued 27 March 2013, replacing Recorded Signed For, but were sold at old rates until 2 April.
  

UPDATE 25 November: SD & RMSF stamps were withdrawn from sale at post offices on 31 October 2021, and also from Royal Mail's online shop.  They continue to be valid for postage at current ratesuntil invalidated on 31 July 2023.

I hope readers find this useful.  It is probably worth reminding everybody that these are also all valid at the rates shown for inland postage, just as the 2nd, 1st, Large, Signed For, and Special Delivery stamps are all valid for services other than those shown and on inland and international mail but will cease to be so from 1 August 2023.
