Why Trust the Read

Honest numbers, not hype

We'd rather tell you a bill is worth face value than oversell it. That's the whole point.

Numismatist-grade reference data

Serial patterns and error types are checked against the same categories collectors and dealers use: ladders, radars, repeaters, and known error classes.

Estimates, never guarantees

BillMarket gives you an informed value range, not a certified appraisal. Most circulated bills are worth face value, and we'll tell you when that's the case, too.

Your scans, your collection

What you scan stays in your collection. No fabricated download counts, no fake reviews, just a tool that does what it says.

FAQ

Questions, answered

Most circulated bills are worth face value, and BillMarket will tell you that plainly. What we look for is the exception: a fancy serial number, a printing error, or a note condition that collectors actively pay a premium for. Scan it and find out either way.
It's a serial number with a pattern collectors seek out: a ladder (12345678), a radar (12344321), a repeater (12341234), a solid (77777777), or similar. Some patterns are common, some are genuinely rare. BillMarket identifies which pattern your serial has and how sought-after it typically is.
BillMarket's value estimate is grounded in real collector-market reference data for serial rarity and error types. It's an informed estimate to guide your next step, not a certified appraisal. For high-value notes, we'd still recommend a second opinion from a professional grader before you sell.
