They are probably bits of rust rather than copper chunks, so the coin is probably worth a few cents at most.
If it's a 1943 steel penny, it isn't worth much...a few cents if it's circulated, or a little more, maybe 50 cents if it's uncirculated. If it's a 1943 copper penny take it to a reputable coin dealer as fast as you can get there. HOWEVER, I can basically guarantee you that it isn't a 43 copper penny, because only about 10 are known to exist. If it's silver in color, it's a steel penny. If it happens to be copper in color, have someone check it out, BUT, it's likely a fake if it's copper.
It's worth 2 cents for its copper content.
