Looks like an RPM to me. Not near my cherrypicker's guide now. I'll check back to see if anyone answers before I get home
I don't see one like that on coppercoins. Is it possible to get a closer straight-on shot of the mint mark?
Ill try. I had to use a magnifying glass to take that picture and was hard to get it to show it where it could be seen. Sorry for the delay Had to restart my phone
The picture is too blurry to see the required detail in order to make an assessment of the mint mark.
