In 2010 there were another 19, because the year was now coded in to the design.
Collectors were confused, dealers were confused, and catalogue editors were confused. Stanley Gibbons catalogue editors managed to assign three different numbers to the same stamp in one year (Concise, Collect British Stamps, and new Concise). And they decided to keep things simple by listing the original stamps, and those with the 2010 code separately.
But when 2011 came, 'keeping things simple' meant having one set of numbers for the stamps with no year code, and another set for those with a year code, no matter what that year was. Which is fine if you want a simple list – but serious Machin collectors wanted every variant, and dealers needed a simple way to identify separately the stamps from each year. With no central plan from SG, many dealers devised their own – different – systems.
The Norvic system is unique in that, bar the unexpected, you can work out what the Norvic numbers will be for any new stamp that is issued in 2014 and beyond at least to 2019. Our Checklist has been prepared and refined with the help of collectors and other dealers. Now that we have agreement from Stanley Gibbons to cross-reference to their numbers, we can make the Norvic Checklist available to all dealers and collectors worldwide.
The list is available to all Machin collectors free of charge - no catches. The Norvic numbers in the checklist are the ones we use in our webshop where you can buy many of the stamps. Note that some collectors (and dealers) record these stamps in greater detail than we do, for instance according to the size of the gap in the security slits, according to the shape of the perforation, or the direction of printing. Ours doesn't claim to be a complete list of Security Machins according to those criteria, but it does list all the basic stamps - and a few extras.
