Best Coin Apps for iPhone [2027: ID, Value, Loupe]
No single app does every coin job. The best free start is PCGS CoinFacts or the NGC app for price guides and population data, plus Apple Magnifier to read mint marks. Photo identifiers such as Coinoscope and CoinSnap name a coin and estimate a value, LuckyCoin tracks a collection, and a loupe app shows mint marks and doubling up close. App values are estimates, not appraisals. We make LoupeLens, which does the loupe part only.
The best free option: a price guide app and the camera you have
No single app identifies, prices, tracks and magnifies coins well. The best free start is two apps from the big grading services plus the magnifier already on your iPhone:
- PCGS CoinFacts (Professional Coin Grading Service) is a free reference for US coins: the PCGS Price Guide, population reports, photos of coins by grade, auction prices realized and variety attributions. It scans the barcodes on PCGS and NGC holders.
- NGC (Numismatic Guaranty Company) is free and verifies NGC-graded coins from the label barcode, shows the NGC Census and NGC Price Guide values for US coins, and runs the NGC Registry for your graded sets.
- Apple Magnifier is free and built in. It zooms, has a flashlight (on or off) and can freeze the image, which is enough to read most mint marks. On iPhones that support macro photography, the Camera app also takes sharp close-ups of a coin.
Add a photo identifier if you have coins you cannot name, a collection tracker once you have more than a shoebox, and a loupe app with more zoom and a dimmable light for die varieties. The mint mark location chart shows where to look on each US coin.

How we compared them
Coin apps do four different jobs, so we sorted them by job first and then looked at:
- Which job it does. Identify a coin, price it, track a collection, or let you see it up close.
- Where values come from. A grading service’s price guide, auction records, or asking prices on marketplace listings, and whether the app calls them estimates.
- Coverage. US coins only, or world coins too.
- What is behind the paywall. Free downloads often limit value estimates or grades until you subscribe.
- Privacy. What the App Privacy section of the listing says, especially whether data is used to track you.
The apps
PCGS CoinFacts (PCGS)
PCGS calls CoinFacts an encyclopedia of US coins, and the listing says the app is free to use. For over 40,000 US coins it has PCGS Price Guide values, the PCGS Population Report, auction prices realized from PCGS and NGC graded coins, photos of coins at each grade (PCGS Photograde), specifications, rarity estimates and variety attributions with photos. Scan the barcode on a PCGS or NGC holder to open that coin’s page. It needs an internet connection. The listing’s last update is from 2024, so check that it runs well on your iPhone.
Choose it if you collect US coins and want price guide values, population data and grade photos in one free app.
NGC (Numismatic Guaranty Company)
Scan the barcode on an NGC label and the app verifies the certification, shows images of the coin for nearly 20 million NGC-certified coins, NGC Census population data and NGC Price Guide values for US coins, and lets you add the coin to the NGC Registry. You can also browse the census by type and grade, and read NGC news. It is free and available in English, Chinese and German.
Choose it if you buy or own NGC-graded coins. Before buying a slabbed coin, compare the coin in your hand with the image in the app: a matching certification number alone does not prove the holder is genuine.
CoinSnap: Coin Identifier (Next Vision)
Take or upload a photo and CoinSnap names the coin and shows its country, year, mintage, rarity and an estimated market price. It covers coins from around the world, and also offers error coin analysis, grading reports with estimated values, and a collection tracker that totals what your coins are worth. Premium features need CoinSnap Premium, a yearly subscription with a free trial. The listing’s App Privacy section says some data, including identifiers and usage data, may be used to track you.
Choose it if you have a jar of unfamiliar or foreign coins and want a name and a rough value to start your research.
Coinoscope: Coin Identifier (Miccron)
Coinoscope has identified coins by photo since 2018. Photograph both sides and its visual search finds matching coins, with the issue year when it can read it. Identification is free and unlimited. Value estimates come from eBay and other online listings, and an Advanced Image Analysis gives a written description. You can save coins to My Collection. The free version shows ads and limits value estimates and advanced analysis per day; Coinoscope Pro removes both. The listing says some data may be used to track you.
Choose it if you want free photo identification and do not mind ads.
LuckyCoin: Coin Collecting App (Stuck at Home)
A collection tracker, and its listing says plainly that it is not a coin identifier. Log each coin with grade, grading service, purchase price, seller, photos and notes, and see set completion by date and mint mark. Its catalog covers US coins and those of many other countries, with values by grade that the developer says update daily from auction and dealer data. A grade estimator works from a photo of a coin you have already identified. It is free with an optional Premium subscription.
Choose it if you want to keep a record of your collection and a list of the dates and mint marks you still need.
Apple Magnifier: the free loupe
Magnifier is on every iPhone. Its zoom is enough to read the mint mark on most modern US coins, and freezing the image lets you study it without holding still. The flashlight is on or off, and maximum zoom depends on your iPhone’s camera. Tilt the phone, or use a desk lamp from the side, so the light skims across the coin instead of glaring off it.
Choose it if you want to read a date or mint mark now and then.
LoupeLens: the loupe part only
LoupeLens does not identify coins, grade them or give values. It is a magnifier with up to 40x zoom on all supported iPhones and a flashlight that stays on while you zoom: press and hold the flashlight button and slide to dim it, so a bright proof or silver surface does not turn into a white glare spot. Tilt the phone for low-angle light that shows doubling, repunched mint marks and die cracks. Tap to take a photo or hold to record video, and both go to a LoupeLens album in Photos, ready to post to a forum or attach to a listing. No ads, no account, no tracking, and it works offline. It needs an annual subscription, which Family Sharing covers.
Choose it if you already know what the coin is and want to read the mint mark, check for a variety or photograph the details. LoupeLens for coin collecting shows the setup.
Which one should you pick?
| If you need | Try |
|---|---|
| To find out what an unknown coin is | Coinoscope (free, with ads) or CoinSnap (subscription) |

| To use a glass loupe and phone together | See iPhone loupe |
| A value you can sell or insure on | A reputable dealer or a grading service, not an app estimate |
What zoom do you need to read a mint mark?
Mint marks on modern US coins are about a millimeter tall. About 10x reads most of them, and 20x or more shows a repunched mint mark, doubled letters or a die crack. Past 10x, rest the phone on a stand or a stack of books about 8 to 12 cm above the coin, and take a photo rather than trying to hold the live view steady. Light from a low angle matters more than the zoom number. If you also look at stamps, minerals or tiny parts, our microscope apps for iPhone roundup covers higher magnification.
Are coin app values accurate?
Treat them as a starting point, not an appraisal. A coin’s value depends mostly on its grade, and a phone photo cannot settle grade: the difference between a lightly worn coin and an uncirculated one is faint friction on the high points, and cleaning shows as fine hairlines that photos often miss. An identifier can also misread a date or mint mark, which on a key date such as the 1909-S VDB cent changes the value completely. Estimates built from marketplace listings reflect asking prices, which are often higher than what coins actually sell for.
Price guides from PCGS and NGC give values by grade, so they are only as good as your grade. Dealers also use wholesale guides such as Greysheet, whose app needs a paid subscription for prices. Before you sell, insure or split an inherited collection, show the coins to a reputable dealer or submit the best ones to a grading service.
Frequently asked questions
What is the best free coin app for iPhone?
For US coins, PCGS CoinFacts and the NGC app are free and come from the two big grading services, with price guides and population data. For identifying a coin by photo, Coinoscope has free, unlimited identification with ads. Apple Magnifier is a free built-in loupe.
Is there an app that tells you what your coin is worth?
Identifier apps such as CoinSnap and Coinoscope give an estimated value from a photo, and price guides such as PCGS CoinFacts give values by grade. Both are estimates. For a value you can sell or insure on, ask a reputable dealer or a grading service.
What is the best coin magnifier app?
Apple Magnifier is free and reads most mint marks. For more zoom, a light you can dim and one-tap photos, a loupe app such as LoupeLens goes up to 40x. Low-angle light makes more difference than the zoom number.
Can an app identify a coin’s mint mark?
Identifier apps sometimes read the mint mark from a photo, but they can misread it, and on key dates the mint mark decides the value. Check it yourself at about 10x to 20x. The mint mark location chart on this site shows where to look on each US coin.
Are coin identifier apps accurate?
They are usually good at naming the type and country of a coin. They are less reliable on grade, die varieties and small details such as the mint mark, so confirm anything that affects value under magnification and in a price guide.
How do I check if a PCGS or NGC graded coin is real?
Scan the barcode on the holder with PCGS CoinFacts (PCGS and NGC holders) or the NGC app (NGC holders), then compare the coin in your hand with the photo in the database. A matching number alone does not prove the holder is genuine.
