Finding old coins in your attic or pocket change can be exciting, but how do you know their financial value? Free coin identifier apps have revolutionized the way collectors identify and assess their coins’ worth—no expert needed!
Whether you’re a complete beginner looking to understand your financial assets or a seasoned collector, these AI-powered apps can instantly tell you what coin you have and its estimated market value. Let’s dive into the top 7 free coin identifier apps you need.
The Best Coin Identifier Apps for Free
1. CoinKnow
Why it’s #1: CoinKnow is the exciting newcomer that’s taking the coin collecting world by storm in 2025. This app brings professional-grade features that most free apps don’t dare to attempt.
What makes it special: It offers copper color classification (RD/RB/BN), Proof finish detection (CAM/DCAM), and automatic rare variety identification. The grading precision hits an impressive 2-point Sheldon Scale accuracy—that’s remarkably sharp for a mobile app!
Our Review:
CoinKnow delivers professional-grade features rarely seen in free apps. The copper color classification and 2-point Sheldon Scale accuracy rival paid services. Automatically detects rare varieties and error coins that other apps miss. Collection management is intuitive. Generous daily free scans make it perfect for serious collectors.
Perfect for: Serious collectors who want precision without paying premium prices. You get free daily scans, which is generous compared to competitors.
The catch: It’s primarily focused on US coins, so international collectors might need a backup app. Also, you won’t find market trend tracking here.
2. CoinValueChecker
Why it’s #2: Right behind CoinKnow, this app combines rock-solid identification with serious market intelligence. It’s one of the rare free apps capable of detecting error coins like DDO, DDR, and missing mint marks.
What sets it apart: Beyond just telling you what coin you have, it gives you real market insights. This can make the difference between thinking you have pocket change and discovering a valuable find worth hundreds or thousands.

Our Review:
Perfect for beginners with simple, intuitive interface. Identifies common coins in under three seconds with engaging historical context. Great for kids and casual collectors. Free version adequate for occasional use. Premium features available but not necessary for basic identification. Best choice for quick, straightforward coin identification.

The downside: Advanced collectors might find it lacks depth on rare or professionally graded coins. It’s great for identification but not comprehensive for serious numismatics.

How it works: Take a photo or import an image, and the AI identifies your coin or note immediately. It’s like having a multilingual currency expert available 24/7.
Our Review:
Truly global coverage handles coins from 20+ countries equally well. Modern design is sleek and pleasant. Fast AI recognition though struggles with very worn coins. Free version has daily scan limits. Higher premium pricing but worth it for world coin specialists and travelers seeking comprehensive international database.
Free vs. Premium: The free version works fine for occasional identifications. If you’re working through a large inherited collection, you might hit limits and need the premium version.
