Machin Definitives 2018

As more new printings of Machin definitives have been announced it seems like a good time to provide a list of those which have been issued or discovered this year.

As well as those already reported in earlier blogposts, I have been told that there are new printings of business sheets with no serial numbers or dates on the rear of the top panel.  The 1st class is M17L but the 2nd class is M18L so we could see first M18L soon.

The 1st Large booklet has also turned up with M18L coding.  My correspondent says that this is the last one he would have expected, but I think the 2nd Large is even less likely.  While I was away I had two Large letters from non-collector sources in different parts of the country.  Both were stamped with 2nd Large from 2009, with source code FOYAL!

For the six new stamps distributed by Royal Mail on 23 May there will be no official FDCs as they are non-visible change (change of printer only).  We will do a limited number of covers.  We will also stock a limited number of date and cylinder blocks.  It will help our ordering if you let us know that you want these.

For the 1st Large booklet and 2nd business sheet referred to above we will show these in our shop as soon as we have stock.  Meanwhile here are pictures.  I understand that the 1st Large booklet stamps exists on backing paper with printing in both directions.

  1. Have Royal Mail decided against their stamps being produced by DLR in Malta instead of Gateshead or are the Walsall printings a stop gap until DLR get up and running?

    1. Good question, and one that we have limited definitive answers to until now. Royal Mail have written:

      "Following a change of printer, from De La Rue to International Security Printers - Walsall, the recent low value 2018 prints constitute a non-visible change."
