The U.S. Mint’s State Quarter Program (1999–2008) brought new excitement to coin collecting by featuring designs celebrating each state’s heritage.
While most state quarters are worth only their face value, some error coins have become highly valuable collectibles, with certain rare examples fetching prices as high as $150 million. Let’s look into some of these incredible errors and what makes them so special.
