Coin identifier & value checker
Scan both sides of a coin and Minti reads the year, mint mark, and type, separates key dates from common ones, and shows what it's worth from the PCGS price guide and live eBay listing data. Catalog your collection and sell your doubles.
How much is your coin worth?
Face value and melt value rarely tell the whole story. Minti values every coin against the PCGS price guide, PriceCharting, and live eBay listings, matched to the exact year, mint mark, and grade band, so a key-date cent, a silver dollar, or a modern proof each get a number grounded in the real market.

See graded vs raw at a glance
Wondering whether a coin is worth submitting? Minti shows a graded price next to raw comps for the same issue, so you can weigh the grading premium against the fees before you send a coin off to PCGS or NGC.
You can also run a Grade Check first. It reads your photos, estimates the coin's condition, and predicts a likely NGC or PCGS grade, so you have a realistic expectation before you pay submission fees. Grade Check is metered: 10 checks a month on Pro and 100 on Collector, with a locked preview on the free tier.
Catalog your coin collection
Organize your coins by type, series, or country in folders that match how you collect. Every coin keeps its images, grade, and current value, and your portfolio total updates as the market moves, so you always know what your collection is worth.
- Set Tracker turns a series into a checklist, showing which dates and mint marks you own, which are missing, your completion percentage, and what the rest would cost to finish. Free on every tier.
- Profit and loss tracking, so you can see what you paid against what a coin is worth, plus realized profit after fees
