Thought it was a pretty penny because it almost looked "lacquered" in nail polish with its shine & toning. Looked closer and the 1993 D looks like DD maybe even full steps on back ... thoughts & comments are appreciated.
Welcome to CCF. Unfortunately you don't have anything of value here. Your coin exhibits Die Deterioration Doubling and is starting to exhibit the so called "zinc rot". Not a doubled die. Also, Full Steps designation (FS) are usually only recognized with Jefferson nickels. Hope this helps.
