Well I thought it would be a good idea to post your best RPM the one with the most speration and the most interesting one. The coin could be any denomination. Here's my Mercury dime 1940 S RPM which is not listed the one that is listed is the 001 and 002 in the coneca listings mine seems to be more more extreme seperation going west. I think mine is not listed and the population for the OO1 is only 1 known and 1 known for the 002 in AU 55. I think mine is a new variety and,you could see mine with the naked eye. JC
my next to largest separated RPM, 1960- D/D RPM-100, on the Sm/Lg date DDO. My largest separation ( total separation), but hard to see 1956 D/D RPM -008 Jim
