We are constantly working with our contacts in Iran, dealers in Europe, and the Scott Catalog to keep our website current, and also supply the New Issues to Scott Catalog. However, things don’t work perfectly each time!
“Space Technology Day”, a strip of 5 stamps issued Feb 3, 2010 is finally listed in Scott as #3029J, and is probably missing from most collections. On the other hand some stamps issued last year are listed in Scott Catalog, but not in the UPU’s website.
There are a number of stamps issued in 2011-12 which are not yet listed in Scott catalog. To keep our website synchronized with Scott, we have moved all these “Unlisted Issues” to Year 2012. As soon as Scott lists these stamps, (either as 2011 or 2012), they will be moved to respective years.
This late listing creates another problem. Since stamps are listed according to "issue date", some may be listed in previous years, and the collectors who follow the New Issues may not know about them. Good examples are Scott #3029A, B, C, D, up to end, as well as Scott 2860a listed in 2012 as part of 2009 issue!
Our recommendation will be to purchase the stamps as soon as they are listed in our website, eventually the catalogs will catch up.
