The idea that a coin worth thousands of dollars could be sitting unnoticed in your pocket change is thrilling for collectors and casual hobbyists alike.

In 2026, the hunt for these hidden treasures continues, with some coins fetching prices as high as $100,000 at auctions. This guide explores six rare finds that could still be in circulation today and how to identify them.
Why Rare Coins Can Be Found in Circulation
Many valuable coins remain in circulation because they were released in large numbers and only later discovered to have unique characteristics. Some were struck with errors, others were produced in limited quantities, and some were overlooked until collectors realized their rarity. With millions of coins changing hands daily, the possibility of finding one of these treasures is real, though rare.
