I found this 1981 p nickel. The line in the “9” is very hard to see, closer inspection showed there was a line but it is very faint. Also the “P” seems doubled but I’m not expert so I’m not 100%.. thoughts please?
Looks like a combination of circ wear and worn die.
For comparison, Coin Facts
Nickels from the early to mid 80s are commonly found with extreme die wear.
Die fatigue on the number 9. Mm is not a dd, probably wear and possibly bits of die chips clogging up the strike. The hunt continues.
