Here is a partial missing clad and a struck through clading that had fallen off. Note the lost of detail when the clading came off after the after the strike.

On the OP's coin it looks like it was found outside and the copper color is on the surface. If carried in the your pocket for a time the silver clading might be seen on the higher points of the devices if carried for a time.
