The 10 Best Free Coin Value Apps In 2025
1. CoinKnow - My Top Recommended
CoinKnow leads the pack when it comes to determining accurate coin values. This app doesn't just identify your coins—it evaluates them with professional-level precision.
What separates CoinKnow from competitors? It's one of only two apps capable of detecting valuable error varieties automatically. If you're holding a 1984 penny error with a doubled die, CoinKnow spots it instantly and adjusts the value accordingly.
The app includes advanced grading features like copper color designation (Red, Red-Brown, Brown) and Proof surface quality assessment (Cameo, Deep Cameo). These details dramatically affect value, and CoinKnow captures them all.
You get daily free scans plus collection tracking tools. For anyone serious about understanding their coins' true worth, CoinKnow is essential.
2. CoinValueChecker™ - Also Great
Coming in at number two, CoinValueChecker excels at providing current market intelligence. Like CoinKnow, it automatically identifies rare errors that command premium prices.
What makes this app exceptional is its comprehensive market analysis suite. Track price movements over time, monitor auction results, set alerts for specific coins, and see where your collection ranks among other collectors.
The app recently helped users discover a 1965 penny error struck on leftover silver planchets—mistakes like this can be worth serious money. CoinValueChecker™ grades coins within 2-3 Sheldon Scale points, giving you reliable value estimates you can trust when buying or selling.
3. HeritCoin
HeritCoin earns its spot at number three by being genuinely free—no hidden subscription traps. With 4.7 stars from over 55,000 users, it's proven its worth.
The standout feature? 3D coin modeling technology that captures every detail for accurate valuation. The AI analyzes your coin from multiple angles and provides market value based on condition and rarity.
It handles both domestic and international coins effectively. While some very old or obscure coins might challenge it, HeritCoin delivers solid value estimates for the vast majority of coins collectors encounter.
4. PCGS CoinFacts
Created by the Professional Coin Grading Service, CoinFacts offers unmatched pricing authority. When you need to know exactly what a coin is worth, this is where professional dealers turn.
Here's the key distinction: CoinFacts isn't an automatic scanner. You identify the coin first, then look it up to get comprehensive value data across all grade levels. For example, once you've determined you have a 1960 penny error with the large date variety, CoinFacts shows you what it's worth in every condition from Good to Mint State.
The pricing comes directly from actual market sales and PCGS auction records. If you're investing in coins or planning to sell, this authoritative data is invaluable.
5. Heritage Auctions
Heritage Auctions takes a different approach to coin valuation—it shows you what coins actually sold for at auction, not estimated book values.
Search their extensive archives to find coins identical to yours and see the hammer prices. This gives you genuine market data based on what collectors are willing to pay right now.
You can also browse upcoming auctions and place bids directly through the app. It's perfect for understanding realistic values and finding coins to add to your collection at fair prices.
6. Coinoscope
Coinoscope provides valuation through its enormous visual database spanning coins from virtually every country. Upload your coin photo and it searches for matches, providing value ranges based on condition.
The app works offline for basic functions, making it ideal for estate sales or flea markets where you need quick value checks. Historical information accompanies each coin, helping you understand why certain dates or varieties command higher prices.
Basic features remain free without pressure to upgrade. It also includes marketplace integration if you decide to buy or sell based on the values you discover.
7. NGC Coin App
The NGC app specializes in values for professionally graded coins. If you own NGC-certified coins or are considering certification, this app is indispensable.
Access population reports showing exactly how many examples exist in each grade—crucial information for determining value. A 1971 penny error might be common in circulated grades but extremely rare in high Mint State, dramatically affecting its worth.
You'll also find authenticity verification tools and grade-based pricing from one of the industry's most trusted authorities. The values are rock-solid reliable since they come directly from NGC's market research.
8. Greysheet Mobile
Greysheet has been the coin industry's pricing bible for decades. Now their data is available on your phone, giving you the same wholesale and retail values that dealers use.
This isn't a coin identification tool—it's purely for checking values once you know what you have. Whether it's a common date or a 1987 penny error with the doubled ear feature, Greysheet tells you both wholesale (what dealers pay) and retail (what you'd pay at a shop) across every grade.
Particularly valuable when negotiating at coin shows or shops. You'll know if the dealer's offer is fair based on current industry standards.
9. CoinSnap
Need a quick value check? CoinSnap delivers instant results with minimal effort.
Snap a photo and within seconds you'll see the coin's identity, estimated value, and grade assessment. The streamlined interface requires no learning curve—perfect for casual collectors or those new to numismatics.
While not as detailed as professional reference apps, CoinSnap provides reliable ballpark values for everyday coins. It's excellent for sorting through a collection to identify which coins deserve closer examination with more specialized tools.
10. Numiis
Numiis rounds out the list with its focus on comprehensive historical information that helps explain coin values. The free trial gives you full access to explore whether it fits your needs.
Filter by year, country, and mint to find your specific coins and understand why certain varieties command premium prices. For instance, learning about mintage numbers and historical significance helps explain why a 1984 penny error might be worth far more than its face value suggests.
Best suited for collectors who want to understand the "why" behind coin values, not just the numbers.
