@601digs: The RPM mean rotate MM. This mean that you will see the MM strike and has the main and behind a second one BUT with different orientation. Majority are versus East, never up. west orientation it is more rare. The RPM could be very well see or can have very small mark of. Hope you bring a nice one here.
I do not collect them, except the photos, but I love them.
PS: OH, the RPM's are part of the Mint Striking History and procedures.
