Reference depth
CoinROI is connected to Numista, the numismatic reference trusted by collectors worldwide.
Numista gives CoinROI real catalog depth instead of generic AI image matching. That matters for world coins, historical issues, bullion, commemoratives, and the long tail of collector variants.
Coverage is not the message by itself. Trust is. When collectors see Numista clearly connected to CoinROI, they immediately understand why the app can identify more than common modern coins.
Features
Built for collectors who care about precision.
Most apps stop at rough image recognition. CoinROI is designed for the real workflow: attribution confidence, reflective surfaces, auction context, spot price, purchase price, and collection-level ROI.
Identify any coin from two photos.
Country, year, denomination, metal, weight, mint, rarity signals, and key market clues in one result.
Track purchase price versus current value.
Measure return on investment per coin and across the full collection instead of keeping disconnected notes.
See melt value and collector premium together.
Real-time gold and silver prices help separate intrinsic metal value from the numismatic side of the story.
Know the right price before you sell.
Auction signals and sold-market references give a realistic range instead of vague catalog assumptions.
A serious reference, not a shallow catalog.
World coins, ancient issues, commemoratives, bullion, historical variants. The long tail matters in numismatics.
Manage the collection from a larger screen.
Review history, exports, and collection-wide value on the web companion when a phone screen is not enough.
Advanced Coin Scanner
Designed for coins. Not for standard product photography.
Coins are difficult subjects: highlights clip, gold shifts warm, silver goes flat, and tiny relief details often decide the attribution.
- Custom white balance for gold and silver.
- Luminosity offset for proof and reflective surfaces.
- Guided obverse and reverse capture.
- Auto capture when the coin is framed and sharp.
Collector insight
Identifying a coin is only the start. Understanding its real value is what matters.
CoinROI brings numismatic knowledge and investment logic together in one workflow, instead of forcing collectors to piece the story together manually.
