Message:: [QUOTE="GDJMSP, post: 8024378, member: 112"]All of the TPGs have a list of varieties that they label on their slabs - but it's a very short list ! And the vast majority of them are US coins. To the best of my knowledge ANACS has the lonest list they recognize, ICG would be next, then NGC, and PCGS comes in last as they have the shortest list. But even the list that ANACS recognizes is but a tiny fraction of the known varieties for US coins - a tiny fraction. And when it comes to world coinage the number of known varieties is several orders of magnitude bigger than that for US coins. And that's really the problem. There are so very, very many varieties out there hardly anyone, indeed if anyone at all, knows them all for US coins alone ! Even if you look at the Cherrypickers Guide and CONECA, the two biggest organizations there are for tracking varieties, even they are are in a constant state of updating on a daily basis. And that's just for US coins ! With world coins literally nobody does it. For world coins, not in a million years. Oh it might in the form of an article, assuming someone would even publish it, but that would be about it. And even then you'd have to do a veritable mountain of research to verify it even was a new variety ! And even that would be beyond difficult because there is simply no, or at best very little, information, documentation about such things that exists.[/QUOTE]
