You’ve probably heard the saying, “A dollar saved is a dollar earned.” But did you know that some one-dollar bills could actually be worth hundreds—or even thousands—of dollars to collectors? Coins aren’t the only valuable currency items; certain $1 bills can sell for over $1,000 depending on their serial numbers. So what makes these bills so valuable? The rarity of their serial numbers is key. Each U.S. dollar bill has an eight-digit serial number, but not all combinations are equally common.
The Bureau of Engraving & Printing sometimes removes unusual number sequences, which makes the bills that pass through those restrictions more valuable to collectors. Here are some of the rare serial number patterns to look for:
Ladder: Numbers in perfect ascending order, such as 01234567.
Radar: The first four digits are the reverse of the last four, like 22211222.
Super Radar: A rarer version of a radar number, where the middle six digits are all the same, for example 23333332.
Repeater: Numbers repeat in sequence, such as 01570157.
Super Repeater: Two digits repeat throughout the entire serial number, like 01010101.
Radar Repeater: Combines radar and repeater patterns, for instance 12211221.
Double Quad: Only two digits appear, with the first four being one digit and the last four another, for example 00003333.
Seven in a Row: Seven identical digits in a row, such as 11111115.
Seven of a Kind: Seven identical digits scattered throughout the number, like 11115111.
Binary: Only two digits are used, distributed throughout the number with less than seven of either, for example 11313111.
Before using cash, take a moment to check the serial numbers on your one-dollar bills. If you spot any of these rare patterns, you could be holding a valuable collector’s item.
