I just picked up a 1964 proof half dollar with a hub doubling error that is classified as a: PR-12-o-II class 2 hub doubling. Crazy set of Abbr. I know! Anyway the doubling has occured at a few locations on the obverse and is very very haed to even pick out...the R and T in liberty is triple spread but very slight. Has anyone else come across a 64 proof half with this error?
Damn! I knew that was coming...! Well I will take some shots with my camera and also try and scan it but these error's are so slight and my equipment is so...well..it's not old really but it's not nikon! I'll get some pic's up ASAP!
