Coin & banknote scanner for iPhone
Know what it's worth.
Point your camera at a coin or banknote. CoinLens reads the type and variety and shows a market reference range — the moment you scan.
① The value
Condition moves the price.
Every scan returns a market reference range, not a vague guess. Pick a grade from Uncirculated to Good and watch the range move with it — the same way the market does.

② The variety
The right variety, confirmed.
Not every coin is the same. CoinLens reads the design, date, and mint mark to match the likely type and variety, with a confidence indicator — confirm it, or fix it by hand if it's off.
- Capture both faces — the date and mint mark tell the variety.
- A confidence ring shows how sure the match is.
- Wrong match? Correct the variety in a tap.
③ The collection
Your collection, totaled.
Save every coin and banknote you scan into a personal collection on your device. Sort, filter, and watch your collection's total reference value take shape as it grows.

FAQ
Good questions, straight answers.
Are the values real prices I'll get?
They're estimated market reference ranges, not appraisals or guaranteed sale prices. Actual prices depend on grade, demand, and where you sell.

No. Your collection, scan history, and preferences are primarily stored on your device. Optional Sign in with Apple and server-backed family features use an account. We use limited PostHog product analytics and AppsFlyer install attribution without IDFA or cross-app advertising tracking.
What happens to the photos I scan?
When online recognition is enabled, a photo you scan is sent securely to the recognition service to look up the coin or banknote. It is not retained after processing, shared, or used for advertising.
Is anything free?
Yes — the collector guides are free to read, in the app and on this site. Full scanning and valuation are part of CoinLens Pro.
How do I cancel?
