These special combinations are known as fancy serial numbers, and they’re far more valuable than most people realize. Collectors love them because they follow patterns that rarely appear in circulation naturally, making each one almost like winning a tiny lottery. Some collector sites and currency forums offer well above face value — even hundreds of dollars in some cases — depending on how rare the sequence is. Wrinkles, folds, or wear don’t matter nearly as much as the serial number itself. If the digits are special, the bill is special.
