What is my 1984-P Roosevelt Dime that has a gold tone to it not gold plated and the edge is all silver and I cannot see and cladding?

Most likely it has been exposed to heat or a chemical that discolored the cupro-nickel cladding. If it's taken on a gold tone that would make the copper edge seem to blend in with the outer cladding. Unfortunately as such it's a damaged coin and has no extra value.
