CoinROI

Scan coins, estimate gold, silver or collector value, then compare with Numista and online listings.

Could your coins be worth more than you think? CoinROI helps you scan, identify and compare gold, silver, collector value and online listings.

The app combines Numista search, obverse and reverse photos, metal spot prices, market comparables and buy/sell tracking to support clearer decisions.

CoinROI brings together details that are usually scattered across notes, photos and websites: country, year, metal, weight, grade, purchase price, sale price, spot prices and collection notes. You keep a structured view of your coins and can quickly find what you own.

With AI-assisted analysis, CoinROI helps read a coin, suggest identification leads and prepare a more reliable search. Searches via Numista give access to a large international numismatic catalog to enrich your records with references, varieties, mintages and collection details. Web search then adds market comparables and observed prices.

For sellers, the Buy / Sell workspace helps select coins for resale, track amounts, compare market signals and prepare a cleaner listing. For collectors, the collection stays usable: local photos, subcollections, history, filters and practical search tools.

Main features:

• Guided coin scan and capture
• Identification and Numista search
• Gold, silver, metal and collector value support
• Market comparables and online listings
• Purchase, sale, value and notes tracking
• Collection records with photos and metadata
• Kroins credits for AI and Numista operations

CoinROI does not replace a professional numismatist. It helps you document, compare and prepare decisions with a more structured workflow.
