A US currency lookup tool that estimates whether a bill’s serial number is worth more than face value.

Why it surfaced

Serial Value resists the usual collector-site excitement: it says most bills are worth exactly what is printed on them, then gives condition-scaled ranges when a pattern may command a premium. Its model counts rarity across issued serials, includes the denomination and the note’s condition, and explains why a folded fancy serial can lose most of its value.
