The term "Copper Penny" typically refers to the one-cent coin produced by the United States Mint, primarily made of copper until 1982. Before this change, the coin was composed of 95% copper and 5% zinc, giving it a distinct reddish-brown color. The design features Abraham Lincoln on the front and the Lincoln Memorial or a shield on the back, depending on the year of minting. In addition to its numismatic value, the copper penny is often sought after by collectors and investors due to its metal content. As copper prices fluctuate, these coins can sometimes be worth more than their face value, making them an interesting topic in both coin collecting and metals investment.
