Hi, i was wondering about the 1956 D variety(listed in the redbook). It's called "D above shadow D". How do i recognize this? Is it a doubled D? Can i just compare it to another D mintmark cent to distinguish a difference? I'm not sure what i'm looking for here. Any suggestions from experienced cent collectors will be appreciated! The variety sure carrys a big premium over the standard 1956 D mintmark. Thanks!
Thank you for the excellant picture! That sure clears it up for me, i had no idea where it was located!
