High prices on eBay for scarce Machin 2nd class coil stamp

The (in)famous Sunday Times Wine Club stamp, the 2nd class self-adhesive coil from the 2010 printing, has recently made a couple of appearances on online auction site eBay.

The first sale, which was for the whole mailshot, complete envelope and contents, sold for what many thought at the time was a too-low price of £56.  Now a single example from kiloware has been chased up to £113 by 6 bidders, and another has just started.  This doesn't have quite the same spray-on postmark as the STWC one so may be from another mailer.  I've been sent a picture of some other examples from kiloware, and while it isn't possible to confirm from the picture that they are all MA10/MRIL I have no reason to believe they are not:

Remember if you see one offered for sale, or find one yourself, that if there are no security slits, this is from the gummed coil, not the self-adhesive.  The perforations on vertical sides will be cut, and probably short; those at the top and bottom may be guillotined or torn.

Bulk Mailers using stamps - a register, with your help

I was given a mailing from Taylor's Port today, a 2nd class blue stamp with a wavy line laser or ink-jet cancellation.  I was hopeful that they were using the same stamps as the Sunday Times Wine Club, but it was not the case.  This is the 'Sunday Times' stamp:

I thought a register of Business Direct Mail users and what stamps they use might be helpful.  so:


April 2011 Royal Mail Royal Wedding - 1st class SA coil 2009 - MRIL MAIL
July 2011  Sunday Times Wine Club - 2nd class SA coil 2010 - MRIL MA10
?? 2011  Taylor's Port - 2nd class Business sheet 2010 - MBIL MA10
---- 2011  One of the credit card companies (agents) sends out new cards using coil stamps but so far seem to be stuck with 2009.

March 2012 update: The British Heart Foundation also uses 2nd class coil stamps, this is the 2009 self-adhesive:

 (Thanks, Michael)
