I've been looking around the forum and sub forums here, looking for suggestions on books or online resources with which I can learn more about identifying VAMs, histories of the various dies, etc. I'm aware of VamWorld.com. Any other suggestions?
I like to read the descriptions and histories, but when it gets right down to trying to tell one from another, I do best with photo comparisons. I'm a "visual guy" and I like the side by side micro photos that show the difference between VAM vs non-Vam, far date vs very far date, etc.
