CoinDuo: Coin Identifier

How much are your coins worth? Find out a whole batch at a time. CoinDuo identifies each coin from both sides, shows a reference value range in US dollars and points out the coins worth a closer look. IMPORT A WHOLE BATCH FROM YOUR PHOTOS Already photographed your coins? Select front-and-back photos of up to 100 coins in one batch. CoinDuo pairs the photos in the order you choose and lets you swap, replace or remove any photo before it identifies the batch. KNOW WHAT EACH COIN IS See each coin's identity, including country, denomination, year and mint mark where visible, with key details and US dollar reference ranges for four condition levels. You can also photograph a single coin or choose its photos from your library. SCAN A PILE HANDS-FREE Set up your iPhone and place one coin at a time. CoinDuo captures each side automatically, and on-screen and voice prompts tell you when to flip the coin and when to place the next one. No tapping the shutter. SPOT THE ONES WORTH KEEPING Your batch summary shows an estimated total and groups coins as Worth protecting, Collectible, Precious metal or Face value, so the coins that matter stand out. Coins that need another photo stay in view until you finish. BRING YOUR EXISTING LIST Import an Excel (.xlsx) or CSV list for free. Review the column mapping and keep your existing coin details and recorded values. Eligible users receive three successful preview valuations in total, shared across list imports. You can then choose to value more rows using available membership scans or scan-pack credits. The original file is parsed on your iPhone; relevant coin details are sent for AI analysis when valuation is requested. KEEP A CLEAR RECORD Organize coins in folders, search your collection and export a PDF or CSV list to keep or hand to your family. Export requires an active membership or a qualifying scan-pack purchase. Saved coins remain available to view and edit after membership ends. SCANS AND MEMBERSHIP Your first 3 single-coin scans are free, subject to eligibility. This is a one-time allowance and does not reset daily. Batch identification requires scan-pack credits. One-time packs provide 100, 500 or 1,000 scans. Credits do not expire or auto-renew. Successful identification or valuation uses one scan; an unsuccessful result or a request for clearer photos does not use a successful scan. CoinDuo Membership is an optional annual auto-renewable subscription with up to 200 scans per membership month for single coins and spreadsheet valuation. Batch capture and batch-photo identification are excluded. When the monthly allowance is used, available scan-pack credits apply. Active members receive 25% more credits when purchasing a scan pack. Eligible subscribers may receive the paid introductory offer shown before purchase; it is not a free trial. Payment is charged to your Apple Account at confirmation. Membership renews automatically unless canceled at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before the period ends. Manage or cancel in your App Store account settings. Local prices, introductory eligibility and renewal terms are shown before you buy. AI results and value ranges may be inaccurate. They are not professional authentication, grading or guaranteed sale prices. Seek an independent specialist's assessment for potentially valuable coins.
