I cannot get a good pic of the MM. It is one of the RPMs for the year. Lets see if you can figure out which one.
2 and 5 have a broken upper post. This eliminates both of them. This will always fall into MM position and die markers.
Yep, it is the FS-504. Die markers don't lie. This one is in the slider category, if sent in could go AU58-MS63. For now it is going into the library of coins album with the other RPM's and Doubled Dies.
