Your post on VAMworld is fine and I understand why you were wondering but there are many other years with VAMs still waiting to be discovered. Even if it is a new 1921, it would probably be considered a scribbling die scratch variety and there are very few people that even collect or care about them, so it would not be the best first
VAM, something like a die break or clashed letter would be more cool of a first.
It is really just too hard to tell if it is a new one without a lot of studying by someone who really knows them. Just a warning about VAMworld though, they might get on you about pictures being oversized. The scribbling scratches photo would be the most important one to many of those that look for a match. Most of the guys there could probably attibute it with one of the regular obv. & rev. pictures plus the close up of the scribbling scratches. Some people have really slow computers and the more pictures the longer it takes to load a page and many will back out before seeing your post.
In 1921 they used what seems like thousands of different die pairs in different combinations to make the coins.
It was the biggest production year for
Morgan dollars ever. The key to identifying them seems to be in the scribbling scratches unless something else pops out, like a die break, doubled die, die gouge, etc.. 1921 is a very difficult year to attribute without some serious knowledge.
If you really want to know the
VAM # Messydesk over on VAMworld has a business called VARslab and he will attribute any Morgan or
Peace dollar for $6 plus postage. It may be worth sending to him along with any other coins you can't figure out later down the road, to save on shipping. The slab won't add to the value of the coin but it might help you understand how to attribute them better by seeing what he comes up with.
Have fun hunting for your next coin. Keep an eye out for die gouges, letter clashes, die breaks, doubling, etc.. Look at some 1878-P coins to really have some fun.
