it is worth about 5 cents unless it is in original (uncleaned and unplated) condition, in which case it may be worth a few dollars. If you could post photos we could help you more.
to CoinTalk sunshine. 1943 US cents were made from zinc-plated steel to save copper for the war effort. Zinc tarnishes to a very dark gray, and if your coin really looks silvery it is either "Reprocessed" - a euphemism for damaged by replating - worth a tenth of a dime on a good day A relatively scarce untarnished original surface coin - probably removed from Daddy's collection to buy candy - worth quite a bit more They are pretty easy to tell apart, so post a picture and get some opinions.
