What is a binary serial number worth?
Short answerA binary serial number on U.S. paper money (using only 0s and 1s) typically adds a small premium over face value, often $5 to $50 for common notes, but can reach hundreds for high-grade or rare issues.
What counts as a binary serial number
A binary serial number contains only the digits 0 and 1. For example, 01011010 or 11100011. Collectors consider these fancy serial numbers because they are easy to spot and relatively scarce.
The rarity depends on the note's denomination, series year, and condition. A binary serial on a worn $1 bill is far less valuable than the same pattern on a crisp uncirculated $100 bill.
- Only digits 0 and 1 appear
- Common on $1 and $2 notes
- Higher denominations command more
- Condition is critical for value
Typical value ranges
For a circulated $1 binary note, expect $2 to $10 over face value. Uncirculated examples might bring $15 to $50. On higher denominations like $20 or $100, the premium can be $50 to $200 or more.
Extremely rare patterns, such as all 0s or all 1s, or binary serials on older large-size notes, can sell for several hundred to over a thousand dollars at auction.
- Circulated $1: $2–$10 over face
- Uncirculated $1: $15–$50 over face
- Higher denominations: $50–$200+ over face
- Rare patterns: $500+
Common mistakes
- Thinking any binary serial is worth a fortune—most are only slightly above face value.
- Ignoring condition; a folded or stained note loses most of its premium.
- Assuming all binary serials are equally rare; patterns like 00000001 are much more desirable than 01010101.
