The listing, Mickey Mouse charm - Vintage?? has ended.
Found among some old things, not sure of it's age. About the size of a nickel, it looks like maybe it was glued to something else at one time. I didn't want to try cleaning it, for fear I might damage it, but maybe you can give it a try! Or use it in a project where the back doesn't show. It is stamped with the copywrite of Walt Disney Productions, so it is authentic.
