Hello and welcome. I've moved your thread from the "Support" subforum to the "US Errors and varieties" subforum.
Unfortunately, your coin is nether an error or variety. It's a perfectly normal 1988
Lincoln Cent, which someone as applied a blowtorch to.
Heating the surface of a penny up to around 400 deg C - a point where the zinc core has almost but not quite started to melt - will cause the copper plating to dissolve into the zinc core, leaving an appearance which is mostly-zinc-coloured. The bubbly surface and lack of oxidation also both point to the coin being blowtorched.
