NoteLens: Banknote Identifier

Photograph a banknote to explore its country, denomination and issue. NoteLens brings visible serial-number details, condition information and a value estimate together, so you can take a closer look before adding it to your collection.

Explore the issue
Take a photo or choose one from your library to review the suggested country, denomination and issue. Correct the match when needed.

Check the serial number
Check the visible serial number and explore its number patterns. Edit a misread number before saving.

Put condition in context
Compare the photo-based condition with an estimate and the explanation behind it. Use the condition options to see prices by condition.

Build your collection
Save an unlocked result, add notes and organize items in folders. Revisit your saved details and identification history as you explore.

Track your collection
Filter saved banknotes by country or condition. See how many countries are represented in the collection or folder you are viewing.

Learn with 12 guides
Read 12 topic guides in step-by-step pages, alongside other in-app articles. No subscription is needed to read the guides.

Ask your next question
Open the assistant from the result page to ask follow-up questions and keep learning. Usage limits are shown in the app.

Understand estimates
Matches and details can be mistaken or incomplete. Values are estimates, not verified sale prices, authentication, offers or financial advice. Actual prices depend on condition, demand and where you sell; condition-specific prices appear only when supplied, and changing a condition may not produce a new estimate. Collection totals summarize saved estimates, not live market changes. Unreadable serial numbers remain unconfirmed, and a photo does not certify a printing error.
