MintProof: Coin Identifier

What is your coin worth? Take two photos and find out, with the price source shown.

MintProof is a coin identifier and coin value checker. It's made for US coins (pennies, nickels, dimes, quarters, half dollars and dollars) and also recognizes many coins from other countries. We built it to fix what collectors hate about coin scanner apps: results that change every scan, prices with no source, and subscriptions that trick you.

SCAN IN SECONDS
• Put the coin in the circle and tap: the circle turns green when it's framed right. Then flip it for the back.
• It reads the date and mint mark printed on the coin. If a worn digit changes the value, it asks you instead of guessing.
• Same photos, same answer, every time.
• No coin at hand? Try a sample coin, or look one up by series and year.

CHECK YOUR CHANGE, EVERY WEEK
• A new hunt every Monday: pennies, nickels, dimes and quarters, halves and dollars.
• The key dates, famous error coins and silver coins to look for, and how to spot each one.
• Scan your change and see what you checked and found this week. Optional Monday reminder.
• Daily quests and a collector level that grows with every find.

WHAT IT'S WORTH, AND WHY
• Coin values for every condition, from Good to Uncirculated, with a suggested grade from your photos.
• Every price shows where it comes from and when it was updated.
• Rarity from the number of coins minted.
• "Worth checking": known error coins, varieties and scarcer mint marks of the same year, like the 1955 doubled die or the 1909-S VDB cent.
• Specifications: metal, silver content, weight, diameter, designer and catalog number.

YOUR COIN COLLECTION
• Every coin with photos of both sides, condition and notes. Same coin again? It's counted as another copy.
• Your collection's total value, your best and rare coins, and how much silver and gold it holds.
• Sets that check themselves off as you scan, like the 50 State Quarters.
• Your own albums, milestones to unlock, and prices that stay up to date.
• Share any coin as a card with its value.
• Coins worth a closer look (key dates, $20 and up) link to their recent sold listings on eBay, and you can sell them there.

FAIR PRICING
• Your first 10 identifications are free, and so are values, the collection, its total and the weekly hunt.
• Invite a friend: you both get 10 more free identifications.
• Premium: unlimited identifications and CSV export.
• No weekly plans. Yearly with a 7-day free trial, or monthly.
• We remind you 2 days before your trial ends.

Values are estimates for typical coins in each condition, based on the Numista catalog. They are not an appraisal or an offer to buy. Rare varieties and certified coins can be worth more.
