The 2001-D Lincoln cent mule error coin, a Lincoln penny mistakenly produced with a Roosevelt dime reverse, is so rare that it has sold for over $100,000 at auction. Struck at the Denver Mint, only a few of these error coins exist, making them highly sought after by collectors. Even those in poor condition can be valued at up to $20,000, demonstrating their rarity and desirability.
