Notes that have serial numbers with digits that ascend or descend are pretty prized. Called ladder bills, the most sought-after are the true or perfect ladder serial numbers 12345678 and 87654321. They are exceedingly scarce and represent only one in 96 million bills printed, hence their high value.
