Looks like PMD there for sure but beyond that I will yield the floor to the Lincoln experts, of which I am not a member.
It looks like die deterioration. The valley in the tail of the 9 looks like a flow line, and the top of the 9, and 8 look like a hit. I know it's unlikely that the hit on the 9 would match the curve. There is no hub doubling though. Look at some examples of 1983 doubled die Lincolns on Coppercoins, Wexler, or Variety Vista. You will see how the numerals have seperation lines, and how much thicker/wider than normal they are.
hey do you no your coins i think i got some interesting coins with errors i need help talk to me people
I'm sure that if respectful and serious, the membership would be happy to assist you. However, in order to best do so, you need to start your own new thread, and be sure to post clear and we'll detailed photos of the coins in question along with written descriptions of what it is you're seeing or that concerns you.
