RareBillLow serial number
A number under 1000, printed with leading zeros: 00000042. These are the first notes off a print run, and the lower the number the more it is worth.
How rare is it? Exactly 999 of the 100,000,000 possible eight-digit serial numbers are low serials — about 1 in 100,100. That figure is counted, not estimated: every possible serial was run through the same engine the RareBill app uses.
How to spot one
Count the zeros at the front. Five or more leading zeros means you are under 1000 and into low-serial territory.

What it is worth
Value climbs steeply as the number falls. A number under 100 is a strong find; a number under 10 is exceptional, and 00000001 is a trophy note.
Condition matters as much as the pattern. A crisp uncirculated note can be worth many times the same serial in worn condition, which is why RareBill shows value ranges with links to current listings rather than a single number.

Only millionth notes, true binaries, seven-of-a-kinds are rarer among the patterns RareBill checks.
