Is a 1943 copper penny a mint error coin?
Could you please clarify for me if a 1943 copper penny is indeed considered a mint error coin? I'm quite intrigued by the concept and would love to learn more about its uniqueness and rarity within the world of numismatics. Could you elaborate on the factors that contribute to its classification as such, and whether there are any specific markings or characteristics that set it apart from other, more common coins of its era?
