Hi Product Hunt! I built Banknote Expert because people often struggle to verify whether a dollar bill has a genuinely collectible serial-number pattern or whether an online rarity claim is supported by evidence. The website currently includes: • A fancy serial number checker • A star note lookup based on BEP production data • A $2 bill serial number lookup • Research guides covering radar, ladder, low and birthday serial numbers • Value information supported by published auction records and reference data The product is free and works directly in the browser without requiring an account. I would appreciate it if you could test the tools with US banknotes you already know and verify the results. If you find an incorrect classification, confusing explanation or technical bug, please mention it in the comments. The purpose of this launch is to collect honest feedback and improve the accuracy and usability of the resource. Thanks!
