The 1943 Lincoln cent, typically made of copper, saw a temporary shift to zinc-coated steel due to copper shortages during World War II. These steel cents are often mistaken for coins made of silver due to their color. However, genuine examples are easily distinguishable with a magnet; steel cents are magnetic, while silver is not. The coloration can vary from a bright, almost nickel-like appearance to a dull gray, depending on storage and environmental factors.
The significance of these wartime cents lies in their historical context and the variations that emerged during their production. Errors, such as copper planchets accidentally being struck in 1943, are highly sought after by collectors, fetching considerable sums. Conversely, steel cents plated after leaving the mint are sometimes misrepresented as valuable errors, highlighting the importance of authentication and expertise in numismatics. The existence of both intentional alterations and genuine rarities creates both opportunity and risk for enthusiasts.
