I only see a possible lamination error, but I am not shure, if it was struck through grease error, a letter, number or design would be missing, if you want you can email me for a photo of a STG penny
Many of the 1982 and 1983 P & D Jefferson nickels have this orange peel and mushy appearance. I think this is one reason why MS65 examples with excellent strike and good step count command high prices. The cause has something to do with overheating , whether it is from annealing the blanks or over production and heating of the dies I am not sure but I think it definitely has something to do with metal flow during the strike.
