You don't really say what you are looking at so I am going to guess and say that it is the rough surface of the coin.

1982 was the first year of the infamous zinc plated cent and the Mint had problems with dust getting caught between the zinc and copper plating. This caused plating bubbles which is what you see on your coin.
