I recently Inherited a few coins, and have no experience with coins. I received 3 $20 gold pieces; an 1877-s in ok condition, 1895-s that looks nice and a 1905 (no mint mark) that also looks nice, I plan on sending these in for grading but have no Idea what they will come back at. I also received a 1921 Morgan (no mint mark) that I can't figure out what it is for the life of me. After hours of online research I am still lost.. is it a cameo, proof of some kind or nothing at all? It has a cool blue tone to it which I believe increases it's value, however I am a total newbie and just don't know. If anyone could help me out with possible grading or a suggestion as to how to submit it I would greatly appreciate it.
