This is not a "filled die" error. Were that the case, the mintmark would be faint. Instead, this is either a case of die deterioration, a mintmark punched-in with a worn punch, or a mintmark rendered "solid" by die chips in each loop. Furthermore, in some years, a "solid" style was used. That's the case with some SBA dollars minted in San Francisco.
ok thanks......I know it wasnt common because I have quite a few of this date and happend to find this one at the shop yesterday. thought it was a RPM until i got home to look better.
