U.S. Coin collecting has always been a fascinating blend of history, artistry, and rarity. While most collectors chase after pristine examples of classic coins, there is another category that often surprises even seasoned numismatists: minting errors. These mistakes, sometimes bizarre and even UFO-like in appearance, can transform ordinary coins into extraordinary treasures. In 2026, error coins continue to capture attention, commanding impressive premiums at auctions and private sales. This guide explores the most intriguing error types, their origins, and why collectors value them so highly.
Understanding Coin Errors
Minting errors occur when something goes wrong during the coin production process. Instead of being discarded, some of these flawed coins escape into circulation. Over time, collectors discover them and recognize their uniqueness. The rarity of these mistakes, combined with their unusual appearance, makes them highly desirable.
Types of UFO-Like Coin Errors
Off-Center Strikes
One of the most common errors is the off-center strike. This happens when the coin blank is not properly aligned in the press. The result is a coin with part of its design missing, sometimes resembling a crescent moon or UFO shape.
Double Strikes
A double strike occurs when a coin is struck twice, creating overlapping images. These coins often look distorted, with ghost-like impressions that collectors find fascinating.
Planchet Errors
Planchets are the blank discs used to make coins. If a planchet is clipped, cracked, or improperly prepared, the resulting coin may have unusual shapes or missing sections. Some clipped planchets resemble flying saucers, hence the UFO-like nickname.
Die Breaks and Cuds
When a die used to strike coins develops cracks, it can leave raised lines or blobs on the coin’s surface. These imperfections, known as die breaks or cuds, create unique patterns that can look otherworldly.
Wrong Planchet Strikes
Sometimes coins are accidentally struck on the wrong metal blank. For example, a dime design might appear on a penny planchet. These mistakes are extremely rare and highly valuable.

Why Collectors Love Error Coins
Error coins are appealing because they break the mold of perfection. Each mistake tells a story about the minting process and human error. Collectors enjoy the unpredictability and rarity, knowing that no two error coins are exactly alike. In many cases, these coins are conversation starters, sparking curiosity even among non-collectors.
Famous UFO-Like Error Discoveries
Over the years, several error coins have gained legendary status. A 1955 doubled-die Lincoln cent remains one of the most famous, with its distorted lettering making it instantly recognizable. More recently, modern coins with dramatic off-center strikes have sold for thousands, proving that error collecting is not limited to older issues.
Investment Potential
Error coins are not only fun to collect but also smart investments. Their rarity ensures that demand remains strong. While common errors may only fetch modest premiums, rare mistakes such as wrong planchet strikes can rival traditional rarities in value. In 2026, auction houses continue to report strong bidding activity for these unusual treasures.
