The 1943 steel cent is worth about five cents in average circulated condition. During World War II, copper was needed for the war effort, so pennies were struck in steel and coated with zinc. While they look unique, most are very common and have minimal value unless in uncirculated condition or a rare error variety.

Don’t clean your coins. Cleaning greatly reduces their value because collectors and investors prefer coins with original, natural toning and surfaces.​

U.S. silver coins are valued mainly by their silver content. Coins dated 1964 and earlier are 90% silver, while Kennedy half dollars from 1965 to 1970 are 40% silver. Their true value is determined by the current melt (bullion) price.​

A coin’s value depends on its date, mint mark, condition, rarity, and demand among collectors. If you think you have a valuable coin, avoid cleaning it and consider having it professionally appraised.
