Help identifying 1971-D Ike variety
Odds that I have some sort of missing link prototype? Pretty much zero, but I am curious as to what's going on with it as I've never seen one quite like it before marked as a 71-D and it does share a surprisingly large number of features between the confirmed Ike prototypes. I'm talking about things like the heavy die polish lines, near-peg-leg with die abrasions south of it, the matte finish, slight cameo appearance on the reverse, serifs matching (not all of them, though hypothetically it wouldn't be exactly the same as the others anyways afaik). Any help would be appreciated. Btw - weight is 22.6 Thanks!
