How to Tell if a $1 Bill Is Valuable

Most dollar bills are only worth a dollar—but a rare few are worth far more. Collectors look for specific combinations of features that make a bill stand out. If your dollar bill matches any of these traits, it might be time to check its value:

Old Series Dates: Bills from the 1920s to 1960s are often more collectible, especially if they're in good shape.
Unusual Seals: Most $1 bills have green seals, but red, blue, brown, or yellow ones can indicate older or military issues.
Rare Serial Numbers: Fancy numbers like low serials (00000001), repeating digits, or palindromes are highly prized.
Star Notes: These replace misprinted bills and are marked with a star at the end of the serial number.
Condition Matters: A crisp, uncirculated bill is worth much more than a worn one—even if they're the same series.

Even small details can dramatically change a bill's value. So hang on to that weird-looking dollar—it might be worth more than lunch!
