Welcome to coin talk! That is PMD (Post mint damage). It looks like somebody took an electric sander to it.
The newer cents have a zinc (silver/grey) core with a copper coating. When something wears through that copper coating you see the zinc core. As @Bluntflame said above, it was sanded smooth so the higher points of the cent now present as grey.
Welcome to CT @Jmann3030. Bored youngsters often do strange things to coins and it appears your cent was rubbed against a rough surface and then turned over and repeated. Why? Anyones guess but guaranteed NOT an error, just PMD, Post Mint Damage, happened after it left the mint.
