Is there a record of a 1993 penny with raised edges that looks to be copper plated aluminum with the plating starting to rub off?
I guess the mint has done a very good job of hiding the composition change that was made back in 1982.

The coating has started to wear off your coin, exposing the whitish-colored zinc core.
