Ancient coin identifier & value checker
Point your camera at a Greek, Roman, or Byzantine coin and Minti reads both sides to help identify the civilization, ruler or type, denomination, and metal, then estimates value from recent eBay sold listings and auction results. Identify it, track it, and sell it, all in one app.
How much is your ancient coin worth?
Fixed catalog numbers rarely match what a coin actually trades for. Minti estimates value from recent eBay sold listings and auction results, so a worn Roman denarius, a Greek silver tetradrachm, or a late Byzantine bronze all get a figure grounded in real sales rather than a static price guide.
- Market-based value from recent eBay sold listings and auction results
- A realistic range for worn and problem coins, not just perfect examples
- Price history across 7-day, 1-month, 6-month, and 1-year windows
Identify any coin in seconds
Not sure what you're holding? Minti's AI reads both the obverse and reverse to help identify the civilization, ruler or type, denomination, and metal, from a portrait and legend to the reverse imagery. Ancients are often attributed by reference catalogs, so Minti gives you a strong starting point to confirm against those references.
- Helps place coins as Greek, Roman, Byzantine, and other ancient issues
- Reads the portrait, legend, and reverse to suggest a likely ruler or type
- Auto-fills metal, denomination, and attributes so your entry stays clean
Authentication and condition
With ancient coins, authenticity comes first. Forgeries and tooled pieces exist, so Minti gives a market-based estimate, not an authentication. For anything of real value, confirm authenticity through a specialist or a grading service. Condition also drives price: wear, strike quality, centering, and surface all move the number, and coins slabbed by NGC Ancients can carry a premium over comparable raw examples.
Organize your coin collection
Keep your ancients in sets and folders that mirror how you actually collect, whether by civilization, ruler, or denomination. Every item carries its images, metal, condition, and current value, and your portfolio total updates as the market moves, so you always know what your cabinet is worth.
Buy, sell & auction in the marketplace
When you're ready to trade, list any coin as a fixed-price Buy It Now or a live auction with anti-snipe extensions. Make and receive offers, accept secure payment through Stripe, and ship with a pre-paid label. Funds are held safely until the buyer confirms delivery.
Ancient coin FAQ
How do I find out what my ancient coin is worth?
Scan the coin with Minti. The AI reads both sides to help identify the civilization, ruler or type, denomination, and metal, then estimates value from recent eBay sold listings and auction results so you see a market-based figure rather than a fixed catalog number.
Can Minti help identify the ruler, type, and denomination?
Yes. Minti reads the portrait, legend, and reverse imagery to help attribute the coin to a civilization such as Greek, Roman, or Byzantine, and to suggest a likely ruler or type, denomination, and metal. Ancients are often attributed by reference catalogs, so treat the result as a strong starting point for confirming against those references.
Does authentication matter for ancient coins?
Yes. Authenticity is central to ancient coins because forgeries and tooled pieces exist, and Minti gives a market-based estimate, not an authentication. For high-value coins, confirm authenticity through a specialist or a service such as NGC Ancients. Note that NGC-graded coins can carry a premium over comparable raw examples.
Is Minti free to use?
Yes. Minti is free to download and includes a monthly allowance of AI scans, plus organizing, value tracking, and marketplace access. Paid tiers raise the scan and storage limits for larger collections.
How do I sell ancient coins on Minti?
List any coin as a fixed-price Buy It Now or a live auction, receive offers from buyers, and accept secure payment through Stripe. Minti generates a pre-paid shipping label and holds funds until the buyer confirms delivery.
