I believe I've found another...this one is kinda hard to see. There is a raised blob above the top right corner of the S that turns out to be the top right corner of the underlying S.
I disagree It certainly is not machine doubling since there is no shelf-like appearance. The second S is faint, but it has texture. Notice that the high points on the S mintmark are where the second S shows strongest. I think it was a too light hit on the punch, it was reset, then repunched. IMO of course.
Just saw something cool Check this out...there's another small blob near the rim...can you barely see that S under there in the picture? I know it's trivial, but so cool!
A blob does not neecessarily a RPM make. Dies do often get dinged up, leading to lumps, bulges, lines, rough spots, et cetera. If it's to have any significant numismatic value it generally has to be considerably more visible than what you've shown, and it should also obviously be something, instead of probably being nothing. In short, in my opinion, based on those pictures, it's nothing. Sorry. Fish
Thanks for the honest response Fish. There is certainly not much raised metal, but there is some. Do you see some of the double die varieties out there? Barely noticable little cracks under high magnification. I'm convinced these are RPMs, as in two different punches of a punch. A light hit makes a light mark. Insignificant? Most probably. The pictures are of low quality, and you lose all idea of depth and thickness that you see with a microscope by adjusting the focus knob. An interesting topic would be...how much of a mintmark should be to be considered a RPM to a numismatist? More than shown here probably, but it's fun to look. Hard to find something new on a popular 63 year old coin! Happy holidays!
