Is Possible To Identify A VAM On XF, Au Morgans ?

I am able to ID the die pairing designation on About Good (AG)Morgans if the pick-up points remain. I believe you may have the common misconceptions about VAMs that most non-vammers have ... i.e., that a VAM is a "thing" on a Morgan/Peace dollar. A VAM is the designation for the obverse and reverse "die pair" used to press the coin in question. Dies came and went throughout the minting process and many were in a constant state of change due to wear and mint maintenance (polishing, re-engraving, etc). If these changes were significant, it resulted in a new VAM designation (this was and still is up to the originator of the study of Morgan/Peace die pairs ... Leroy Van Allen). What you are referring to are pick-up points or PUPs that are used to identify the die pair.

Hope this helps. There's much more information in the Classic Coin, VAM section.

The current number of designated VAMs is around 5000. There are "hundreds" of 1878-P's alone. The overwhelming majority of them aren't worth additional money - remember, we're talking about identifying individual dies, not individual errors - but some are worth significant money indeed.

All Morgans are VAMs. We just don't know about some of them yet.
