this is a photo of the "D" mint mark on a 1975D
LMC. coppercoins website lists only two RPM's, and as much as I am clear that this is NOT one of them, and I am also sure that the ding at the top of the "D" is contact damage, the bottom of the mint mark does NOT look like damage. it also does not look like the many examples of "
Machine Doubling" whih I have posted in the past. can anyone help explain what might be going on with this mint mark. thanks.
