The item in question pertains to a United States one-cent coin produced in 1943, mistakenly struck using steel planchets intended for wartime production instead of the copper alloy typically used for that coin series. The expected composition of this series during that year was a zinc-coated steel, giving it a silver-like appearance. This deviation from the intended metallic composition created a significant anomaly.
These errors hold considerable value and historical significance due to their rarity. During World War II, copper was a critical resource prioritized for military applications. The intended shift to steel for cent production aimed to conserve copper for the war effort. Consequently, those examples produced on bronze planchets from the previous year are highly sought after by collectors. The allure stems from their scarcity and the fascinating story behind their unintended existence, a direct result of wartime exigencies.
