What this coin looks like (obverse, reverse, mint mark location, special features, etc.): 1943 Lincoln Wheat Cents look like "silver pennies" but they are actually made out of steel. During World War 2: The US needed to allocate as much copper as possible for the war effort and this included copper used for minting Lincoln Cents at the US Mint. Zinc-coated steel was used as the substitute metal composition and hence the new silver-like coin is known as the wartime steel cent or steel penny.
