It's rusted, heavily scratched/gouged and has very obviously been replated. GTG? Don't make me laugh.
Did you genuinely believe this was an error? It looks like someone took a knife and tried to cut the coin in half.
It also looks like one of those replated steel cents I see on ebay. Those gouges also kill the coin. The rust spot does not help either. My guess is no grade from TPGS.
Here's what a replated 1943 cent looks like. Those gouges could be from the clippers while hold the coin while being plated.
The 1943 steel cents planchets were cut from a strip of steel that had already been zinc plated. An original 1943 cent should show no sign of the edge having been plated. A reprocessed/replated 1943 cent will have plating on the edge. The OPs coin is only worth one cent.
