Just wondering if any of you have a clue what this could be from? Sorry the pics are not the greatest.
This. 1921 San Francisco Morgans were minted to the outside limit of die life. These "tails" on peripheral letters can be observed on other Morgan issues, but 1921-S is rather notorious for their high proportion of egregious examples. Between that, predominant heavy polishing and the generally weak strikes, I'm tempted to believe they were in a bet to see how many coins they could average from their dies.
