I was looking through some coins the other day and I found another RPM. So the first thing I did was look at the Cherrypicker's Guide to see if it was in there. There is a possibility that it is the one shown on page 206, URS-4 - I-3 - L-3, though I think my secondary  D may be south and east of the primary D. There doesn't seem to be any other doubling on this coin, which would indicate the re-punching also.
