I haven’t seen any listings for this. I could be wrong; I usually am. Just curious to see what you think. The lower half of the reverse, particularly “MONTICELLO” and “CENTS” looks doubled to me. Not to knowledge about nickels FYI
Very common I saw that on a lot of nickels the word cents mostly sorry M/D. D/D are 2 of the same side by side not one on top of the other and yes you are seeing two.
