Frequently asked questions

AI Coin Collector is an app that identifies coins from a photo, shows what the Numista catalogue knows about it (value per condition, mintage, rarity, background), and helps you organise your collection. It also has a community, achievements and coin news.

Yes. The free plan includes daily free scans and a collection to get going. Premium adds more scans, bigger collections and value history, with a free trial. See the pricing page.

Recognition works best on clear photos of common coins. Rare, worn or damaged coins and poor photos are harder, so the app shows every result as a suggestion you check and can correct. We do not quote an accuracy percentage: we have not measured it on a large public test set yet. Treat every identification and value as an estimate, and check valuable coins with an expert or a professional grading service.

The app is coming to Android first, through Google Play. An iPhone version is planned for later. Your collection is stored in your account, so you get it back when you sign in on another phone.

Circulation coins, commemoratives and world coins from many countries, from modern back to older issues. Coverage is best for widely collected coins and keeps growing.

Use good, even lighting (daylight works well), place the coin on a contrasting background, let the coin fill most of the frame, hold the camera steady, avoid shadows and reflections, and keep the whole coin in the frame. Adding a photo of the back helps the match.

Correct the name, country, denomination or year in the form before you save the coin. Very rare coins, damaged coins and blurry photos are the most common causes of mistakes.

An open vision model on our own AI server in the Netherlands reads your photo and suggests country, value and year; you see it as a suggestion and check it before saving. No Google or other outside AI service sees your photo. Scanning needs an internet connection.

The free plan includes a collection to get started; Premium allows bigger collections. For each coin you can note the purchase price and your own notes.

Yes, every collection can be exported to CSV, and you can download all your data (GDPR export) in the app. For importing an existing collection from a spreadsheet or another app, email support@aicoincollector.com and we will help.

The app shows the catalogue price per condition (VG to UNC) from the Numista catalogue, in euros. That is a reference value, not a sale price or an offer: what a buyer pays depends on condition, demand and where you sell. Rarity comes from the mintage of that coin in that year.

Yes. Collections are private to your account.

No. Buying, selling and trading between collectors is not in the app, and there is no date for it yet.

Post a find with a photo, ask for a second opinion, like and comment, and follow other collectors. You get a notification when someone likes, comments or follows. You can also report or block other users.

You earn XP for scanning and taking part, unlock 15 achievements, keep a daily streak and climb the leaderboards with challenges.

Traffic is encrypted in transit and data is encrypted at rest. We do not sell personal data. The privacy policy lists exactly what we collect, why, and which providers process it.

You can delete your account in the app or through the account deletion page. After a 30-day recovery window your personal data is permanently deleted or irreversibly anonymised, except invoices we must keep by law.

We never store full card numbers. Subscriptions are processed by Google Play or Stripe; we only receive what we need to manage your subscription.

Premium adds more scans, bigger collections and value history, and you can try it free first. Google Play shows the price for your country before you pay.

Yes. Cancel in Google Play under Payments and subscriptions. Paid features stay active until the end of the billing period, then your account returns to the free plan.

Check your internet connection and lighting, try a different angle, clean the camera lens, update to the latest app version and restart the app. Still stuck? Email support@aicoincollector.com with an example photo.

Make sure you are signed in to the same account on both devices, check your connection, and try signing out and back in.

Restart the app, update to the latest version, restart your device or reinstall the app. If it keeps happening, email support@aicoincollector.com with your device model.
