New to collecting and found this Dime today, any thoughts on what is going on with it would be appreciated. Appears to be a rough finish, missing layer? Thanks again
Appears to be ED, Environmental Damage. May have been exposed to some acidic situation, causing the surface to become damaged (dropped in a cup of Coke™?). Others will no doubted give their opinions, so hold on for a bit and see what they have to say.
I have metal detected dimes and other coins from the beach that have that appearance. Years of tumbling in the sand gives it that roughness. Not a mint error of any kind.
Missing clad layer usually happens only on one side of a clad coins.. Here are examples from my collection
