Never heard of that animal before.. I've seen the '73 and '75 misplaced mint mark (High) that were next to the last digit of the date but this is a new one to me...
This one is low, but without a standard to check against, I have no idea about how low it needs to be.
Lol right. I made a half-hearted attempt to find some info earlier but came up empty other than a few listed for sale. Saw one listing for $5.00 and another for $4.99. Not a bad little margin for a nickel lol. I'll do some more poking around when I have more time and try to come up with some type of MM placement guide somewhere or something unless the OP or someone in the know can provide it?
I don't believe it is the 73D that has the high misplaced MM. The Low MM needs to be touching the Queue/ribbon in order to qualify for the low MM. This is the High MM it is on a 75D You can find it in Variety Plus. https://www.ngccoin.in/variety-plus/united-states/nickels/jefferson-five-cents-1938-date/819769/ 1975 D MISPLACED MINTMARK 5C MS NGC Attribution: MISPLACED MINTMARK Cross Reference Fivaz-Stanton (NEW): FS-401 Diagnostics The mintmark was placed far too high, nearly touching the date. Though the placement of mintmarks varied from die to die until the 1990s, this one is so far from ideal that it has attracted much interest from collectors.
