How to Identify a Coin From a Photo
To identify a coin from a photo, photograph both sides in soft, even light, read the country name, date and mint mark, then match the photo against a coin catalogue. The fastest way is a coin identifier: CoinReader reads the coin's inscriptions free in your browser, and the Coin Value Checker app recognises the coin itself among 450,000 varieties.
Identify your coin from a photo
Upload a photo of each side. The inscriptions are read right in your browser — nothing is uploaded to any server — and matched against the worldwide catalogue.
· The short version ·
Identify a coin from a photo in five steps
- Photograph both sides. Use soft daylight, no flash, a plain background and the phone held parallel to the coin. Fill the frame and make sure the date is sharp.
- Read the inscriptions. Find the country name, the denomination, the date and the mint mark. These four details identify most modern coins on their own.
- Convert the date if it isn't Western. Islamic, Thai, Japanese and other calendars are common on world coins and convert with simple arithmetic.
- Note what the photo can't show. Measure the diameter, weigh the coin and test it with a magnet. Size, weight and metal separate coins that look the same.
- Match the photo to a catalogue. Upload the photo to a coin identifier such as CoinReader, or photograph the coin with the Coin Value Checker app, then compare the reference images with your coin.

The best ways to identify a coin by photo
A dedicated coin identifier beats a general image search, because it matches your photo against a coin catalogue and returns the exact type, years and value, not just look-alike pictures.
| Method | How it works | Best for |
|---|---|---|
| CoinReader photo identifier (this site) | Upload a photo of each side; the inscriptions are read in your browser and matched against the worldwide catalogue | Coins with readable text. Free, no sign-up, the photo never leaves your device |
| Coin Value Checker app (iPhone) | Recognises the coin itself, not only its text, among 450,000 varieties | Worn coins, foreign coins, varieties and a value estimate for the coin's condition |
| Google Lens | General reverse image search across the web | Naming common modern coins quickly; rarely gives the exact variety, mint mark or value |
| PCGS CoinFacts, NGC Coin Explorer | Reference catalogues you browse by series and date | Confirming US coins once you know roughly what you have |
| Collector forums | Post photos and experienced collectors reply | Oddities and ancient coins; answers can take hours or days |
1. CoinReader photo identifier — free, in your browser
Use the photo identifier at the top of this page and upload a photo of each side. The text on the coin is read on your own device, nothing is uploaded to a server, and the matches come from a worldwide catalogue of 200,000 coin types. If you can already read the coin, you can also search for it by name. One full identification with prices is free each day.
2. Coin Value Checker app — when the text isn't enough
The app goes further than reading text: it recognises the coin's design, so worn, dirty and foreign coins can be identified too. It names the country, denomination, years and metal, shows reference images to confirm the match, and estimates the value for your coin's condition. It's free to download, rated 4.5 stars on the App Store, and the first identification is free.

How to photograph a coin for identification
A sharp, glare-free photo of each side is what makes identification work. Most failed matches come from blur, glare or a date hidden in shadow, not from the identifier.
- Use soft daylight, not flash.Flash bounces off the coin's surface and hides the date. A window on a cloudy day is ideal.
- Light worn coins from the side. A lamp held low to one side throws shadows across faint details and makes worn dates readable.
- Hold the phone parallel to the coin. Shoot from straight above, about 15–20 cm away, and zoom in 2× rather than moving closer. Close-ups with the wide lens bend the coin out of shape.
- Use a plain, dark background.A sheet of paper or a dark cloth lets the identifier find the coin's edge.
- Tap to focus on the date. The date and mint mark are the smallest details that matter most.
- Photograph both sides, and the edge if it's unusual. The obverse usually names the country; the reverse names the value.
- Don't clean the coin first. Cleaning can cut its value in half. Photograph it exactly as you found it.
· Step 2 ·
What to read on the coin
Four details identify most modern coins: the country name, the denomination, the date and the mint mark. Here is where to find each one.
| Detail | Where to look | What it tells you |
|---|---|---|
| Country name | Around the rim of the obverse (the head side), often in the local language | Where the coin is from. US coins say UNITED STATES OF AMERICA, usually on the reverse |
| Denomination | Usually on the reverse, as a number or a word | The face value and the currency |
| Date | Near the portrait or at the bottom of either side | The year of minting, which narrows the type to one issue |
| Mint mark | A small letter near the date on most modern US coins; on many older ones, on the reverse | Where the coin was struck. US marks: P, D, S, W, and the historic O and CC |
| Portrait or emblem | The obverse | The ruler, era or design series, even when the text is worn away |
| Edge | The rim, seen side-on | Plain, reeded, lettered or decorated edges separate look-alike coins |
Country names that don't look like country names
Many coins name their country in the local language or in Latin. These are the ones that puzzle people most often:
| Inscription on the coin | Country |
|---|---|
| HELVETIA | Switzerland |
| MAGYAR / MAGYARORSZÁG | Hungary |
| SUOMI | Finland |
| ÉIRE | Ireland |
| POLSKA | Poland |
| DEUTSCHES REICH / BUNDESREPUBLIK DEUTSCHLAND | Germany |
| ΕΛΛΑΣ / ΕΛΛΗΝΙΚΗ ΔΗΜΟΚΡΑΤΙΑ | Greece |
| CCCP | Soviet Union (USSR) |
| D·G·REG·F·D (with a monarch's name) | United Kingdom |
| 日本国 | Japan |
| 中国人民银行 | China (People's Republic) |
· Step 3 ·
Dates that don't look like dates
If the year on a coin looks far too large or too small, it is probably not a Western date. Convert it with these rules before searching.
| Calendar | Convert to AD | Example |
|---|---|---|
| Islamic (Hijri, AH) | AD ≈ AH × 0.97 + 622 | 1400 AH ≈ 1980 |
| Iranian solar (SH) | AD ≈ SH + 621 | 1380 SH ≈ 2001 |
| Thai Buddhist era (BE) | AD = BE − 543 | 2560 BE = 2017 |
| Japanese era | Shōwa + 1925, Heisei + 1988, Reiwa + 2018 | Heisei 10 = 1998 |
| Hebrew | AD ≈ Hebrew year − 3760 | 5784 ≈ 2024 |
· Step 4 ·
What a photo can't show: size, weight and metal
Some coins look identical in a photo and differ only in metal. A ruler, a kitchen scale that reads to 0.1 g and a fridge magnet settle most of these cases.
- US cents. Copper cents (1959–1982) weigh 3.11 g; zinc cents (1982 onward) weigh 2.5 g. Both were made in 1982, so the scale tells them apart.
- Silver dimes and quarters. A pre-1965 silver dime weighs 2.50 g against 2.27 g for a clad one; a silver quarter weighs 6.25 g against 5.67 g. Silver coins also show no copper stripe on the edge.
- The magnet test.Silver, copper and nickel coins don't stick to a magnet. A 1943 "steel penny" does, and a 1943 cent that doesn't stick could be the famous copper error, or a plated fake.
- Diameter. Measure across the coin in millimetres. Catalogues list it for every type, and it rules out look-alikes from other countries.
· Step 5 ·
When there's no readable text
Worn, corroded and ancient coins can still be identified from their design. The portrait, the shape of the crown or wreath, an eagle, shield or animal, and the style of the lettering that is left all narrow the coin to a country and era. Image recognition in the Coin Value Checkerapp compares these shapes against reference images rather than relying on text, which is why it can name coins that a text reader can't.
For ancient Greek and Roman coins, treat any photo match as a starting point. Their dies were cut by hand, so every coin is slightly different; a specialist dealer or forum should confirm a valuable one.

Common mistakes when identifying coins
- Calling damage an error. Scratches, dents and discoloration that happened after minting add no value. Real mint errors, like a doubled die, appear on every coin from that die.
- Missing a replica. Copies of famous rarities are common. Many are marked COPY, often on the edge or the reverse.
- Confusing tokens and medals with coins. Game tokens, transit tokens and commemorative medals have no face value and are catalogued separately.
- Pricing from a single record sale.A headline auction price is for a coin in near-perfect condition. Check the value for your coin's actual grade in the coin value guide.

After you know what it is
Once the coin is identified, the next question is what it's worth. Check its value by name, read how coin values are decided, or browse values for US pennies, dimes and quarters.

Identifying coins by photo FAQ
How do I identify a coin from a picture?
Photograph both sides in soft, even light, then upload the photos to a coin identifier. CoinReader reads the inscriptions in your browser for free; the Coin Value Checker app recognises the coin itself among 450,000 varieties and shows its estimated value.
Can Google Lens identify coins?
Google Lens can name many common modern coins because it searches the whole web for similar images. It usually can't tell you the exact variety, the mint mark or the value for the coin's condition, which a dedicated coin identifier does.
What is the best app to identify coins from a photo?
Use a dedicated coin identifier rather than a general image search. Coin Value Checker matches a photo against 200,000 coin types and 450,000 varieties and shows a value estimate; it has a 4.5-star rating on the App Store and the first identification is free.
How do I identify a coin with no date or a worn date?
Rely on what's left of the design: the portrait, the emblem, the wreath or shield, plus the coin's size, weight and color. A photo taken with light from a low side angle makes worn details stand out. Image recognition can usually narrow the coin to one type and a date range.
Where is the mint mark on a coin?
On most modern US coins it is a small letter near the date on the obverse: P for Philadelphia, D for Denver, S for San Francisco, W for West Point. On many older US coins, such as the Morgan dollar, it is on the reverse.
Should I clean a coin before photographing it?
No. Cleaning leaves fine scratches that collectors spot immediately and can cut a coin's value by half or more. Photograph it as it is; a soft dry brush to remove loose dust is the most you should do.
