I have a 1952 S Roosevelt Dime Silver that has what looks like a PMD on the Bottom of the Earlobe. Also "Liberty" . 1952 look doubled especially the "2" also "In God We Trust". The Reverse the Mint Mark "S" looks like it is maybe repunched mint mark? Check the pictures thanks a lot again!!
I see some die wear and PMD on the ear , the mintmark has some tiny die chips along the edge of it. when dies are used too long the mint workers tries to grind and polish them for extended die life , this sometimes leaves scratches and gouges on the die.
