What is a “Ladder” Serial Number on a $1 Bill?
Ladder serial numbers are incredibly rare patterns found in the serial numbers printed on U.S. currency.
- These serial numbers consist of a perfectly ascending or descending sequence of numbers.
- For example:
- Ascending Ladder:
12345678 - Descending Ladder:
87654321
- Ascending Ladder:
- They are called “ladders” because the numbers climb or fall like steps.
These sequential notes are extremely difficult to come across, and that rarity is what fuels the skyrocketing collector interest.
