[QUOTE="19Lyds, post: 2371435, member: 15929"]IMO, it is not the RPM but merely ghosting (Flat Field Doubling) caused by the fact that all proof coins are literally struck at least twice. I submitted one of these to James Wiles with the following response:\ [ATTACH=full]484943[/ATTACH] Scratch that thought as I was looking at the FFD. You might have a winner. Better yet, forget everything I say on this particular subject since I had to go through 11 1968 Proof sets just to find a NORMAL Mint Mark. So, I really have no idea based upon my current inventory. Normal (The only 1 of 11) [ATTACH=full]484953[/ATTACH] What I typically have which, yes, does have MDD at the base of the mintmark but the mid-loop and upper loops do not appear normal. [ATTACH=full]484954[/ATTACH] [ATTACH=full]484955[/ATTACH] [ATTACH=full]484956[/ATTACH] [ATTACH=full]484957[/ATTACH] So as you can see, my views are somewhat tainted.[/QUOTE]
