I certainly appreciate the product (figuring out the die variety) of vamming Morgans, but i absolutely loathe those 2 particular years. You know which years I'm talking about if you [mostly] like to find the VAM... 1878 and 1921. I've had my hands on enough of the 7TF 78's and have somewhat gotten used to it, but just picked up my first 7/8 coin and it's driving me crazy! I think I'm taking a short break from this one. Otherwise, I might end up with a coin-sized hole in the wall with my neighbors finding themselves a strange new (old) coin in their possession
For 1921, I think there's over 500 VAM varieties. Needless to say, a 1921 I had sported some die cracks, but I eventually gave up on vamming. Out of the Morgans I own or once owned, an 1884-O is the only one I've successfully vammed. VAM-10, O/O, looks like doubled date (likely not), in an NGC MS64 slab.
I love VAMS with major clashes, and some doubled dates. Doubled ears make me cross eyed and sometimes I start seeing things that aren't there. I don't even look for them on 1921s, I'd end up in a padded cell. I'll bet the TPGs despise attribution on them as well. One of my favorites is the 1886 3+2 clashed reverse. No missing that one, it jumps out and screams at you. I own two of them, one just came back MS67 VAM1-C. A shocking find in the internet wild, and for around $50. I posted it on Coin Talk recently. PCGS, population 10 for attribution and grade, none higher. Here is another. Since these photos (sellers), VSS has attributed this basement slab as VAM 1-C as well. Sometime in the near future, this will be sent to PCGS to crack out and cross over, no minimum grade, whatever it grades at, it slabs at. It is also a beauty with die polish lines and attractive rim toning, but with a very small lamination chip on Liberty's face.
Good luck with the VAM. I love all Morgan and Peace Dollars no matter what condition they are in. Thanks for the post nice Morgan.
