Some US coins and bills are worth way more than their face value—think millions! These rare pieces of money are treasures for collectors, and their value comes from history, rarity, and sometimes even mistakes during minting. From old coins with tiny errors to bills with unique serial numbers, here’s a look at the most expensive US money still out there, waiting to be found.
Coins That Cost a Fortune
The priciest US coins are often from the early days of the country or have special flaws that make them one-of-a-kind. Take the 1933 Double Eagle, a $20 gold coin. Only a few exist because most were melted down during the Great Depression. One sold for $18.9 million in 2021, making it the most expensive coin ever auctioned! Another gem is the 1913 Liberty Head Nickel, with just five known copies. One fetched $4.5 million recently. These coins are super rare because they were never meant to be released or were made in tiny batches.
Error Coins: Mistakes Worth Millions
Sometimes, a mistake at the mint creates a coin that collectors go crazy for. The 1955 Double Die Lincoln Penny is a famous example. The date and words on this penny look doubled because of a minting error. A high-quality one can sell for over $1.5 million! Another is the 1969-S Doubled Die Lincoln Cent, which has a similar error and can go for $2 million or more. These coins are hard to spot, but finding one in your change could make you rich.
Rare Bills with Big Price Tags
Paper money can also be worth a fortune, especially if it has a unique serial number or historical value. The 1890 $1,000 Treasury Note, nicknamed the “Grand Watermelon” because of its green zeros, is one of the rarest. Only a few exist, and one sold for $3.3 million. Bills with “fancy” serial numbers—like all 1s or repeating digits—can also fetch thousands. For example, a $1 bill with the serial number 00000001 sold for over $10,000. Check your wallet—you might have a winner!

Why Are These So Valuable?
The value of these coins and bills comes down to a few things: rarity, condition, and demand. If only a handful of a certain coin exist, collectors will pay big bucks to own one. The condition matters too—a coin in perfect shape is worth more than one that’s scratched or worn. Historical significance also plays a role. For example, coins from the early 1800s or tied to big events like the Gold Rush are prized for their story. Collectors and investors drive up prices at auctions, making these items some of the most expensive money in circulation.
Could You Find One?
Believe it or not, some of these treasures could still be out there. Old coins might show up in a family heirloom or a dusty attic box. Paper bills with unique serial numbers could be in your wallet right now. Experts suggest checking coin collections, old piggy banks, or even loose change for rare dates or errors. If you think you’ve found something special, get it checked by a professional appraiser. You might be sitting on a million-dollar piece of history!
