Frequently Asked Questions

CoinVault Pro is a comprehensive AI-powered coin recognition and collection management platform. It helps collectors identify coins instantly, organize their collections digitally, connect with other collectors, and trade coins safely in our marketplace.

Yes! We offer a free plan that includes 10 coin recognitions per day, up to 3 collections, basic marketplace access, and limited social features. Premium plans unlock unlimited recognitions, advanced features, and priority support.

Our advanced AI system achieves 95%+ accuracy on common coins and 85%+ accuracy on rare coins. We use multiple AI providers including Google Gemini, TensorFlow, and rule-based systems to ensure the highest accuracy possible.

CoinVault Pro works on iOS 14+, Android 8+, and modern web browsers. The app synchronizes across all your devices automatically, so you can access your collections anywhere.

Our AI can identify coins from 195+ countries, spanning ancient to modern times. This includes circulation coins, commemoratives, ancient coins, world coins, US coins, tokens, and even some medals. We're constantly expanding our database.

For optimal results: use good lighting (natural light preferred), place coins on a contrasting background, ensure the coin fills most of the frame, hold the camera steady, avoid shadows and reflections, and capture both sides if possible.

You can manually correct the identification and provide feedback to improve our AI. Very rare coins, damaged coins, or coins with poor photo quality may be challenging to recognize. You can also consult our expert community for help.

We combine Google Gemini AI, TensorFlow models, and rule-based systems. If one system is uncertain, others provide backup identification. This multi-layered approach ensures maximum accuracy and reliability.

Free users can create up to 3 collections, Premium users up to 50, and Pro and Dealer users have effectively unlimited collections. Each coin entry can include multiple photos, detailed notes, condition grading, and purchase information.

Yes! We support CSV file imports and can help migrate data from other collection apps. Contact our support team for assistance with bulk imports or data migration.

We aggregate pricing data from multiple sources including recent auction results, dealer catalogs, market trends, and numismatic databases. Values are updated regularly and consider coin condition and rarity.

Marketplace commission depends on your plan: 7% on Free, 5% on Premium, 3% on Pro and 0% on Dealer. Every sale is protected by escrow and a dispute-resolution process, and higher tiers pay progressively lower fees.

Sellers can list coins as auctions with starting prices and duration (1-10 days). Buyers can place bids, set maximum amounts for automatic bidding, and receive notifications when outbid. The highest bidder when the auction ends wins the item.

Use the 'Report Issue' feature immediately or contact support. We investigate all disputes, hold funds in escrow until resolution, and have policies to protect both buyers and sellers. Our team mediates disputes fairly.
