The Best Coin Grading Apps To Determine Your Coin’s Grade, Rarity, And Value!

by Joshua McMorrow-Hernandez

Looking for a quick way to determine what condition your coins are in?

There’s an app for that!

There are actually many coin grading apps out there. (Or at least coin collecting apps with features that will help you more accurately grade your coins.)

Let’s explore some of the best coin collecting apps for grading coins…

The PCGS CoinFacts App Makes Coin Grading Easy

The Professional Coin Grading Service (PCGS) CoinFacts app is actually many tools wrapped into one handy package — with coin grading being one of its terrific resources.

PCGS Photograde has been helping coin collectors grade their coins for years now, and PCGS has bundled together its coin grading resource into its expansive and highly informative PCGS CoinFacts app.

You might say coin grading has never been as simple as it is now — when using the PCGS CoinFacts app to grade coins!

While the app won’t actually grade the coins for you, what it will do is provide you with high-resolution full-color photos of each major coin type in the various grades.

Photos of the coins range from the grade of Poor-1 to Mint State-70, making it easy to compare your own coins with those in the pics to determine exactly what grade your coin is.

So every single penny, nickel, dime, quarter, half dollar, and dollar coin you own can be looked up on this app! From there, you should be able to tell what grade each of your coins is in.

With the PCGS app for grading coins, you can grade your coins with ease using just your smartphone!

Besides coin grading, other benefits of the PCGS CoinFacts app are:

  • Access to the PCGS Price Guide for coin values
  • Detailed specs and info on a wide variety of coins
  • Even population data for rare coins

It’s one of the best coin collecting apps around, and it consistently ranks among the top coin apps.

The eBay App Has Coin Grade Photos That Are Helpful

One app that may not be on the radar of most coin collectors is the eBay app — it’s awesome for grading coins!

You can use it to search through all of the different coins that are for sale on the popular online auction site.

All you need to do is type in the name or kind of coin you want to grade in the search field and ZOOM to see photos of all the coins for sale — many with their grade mentioned in the sales listing.

There is one major difference between the PCGS app and the eBay app: The grades on the PCGS app are accurately paired with the photos of each coin in each grade. However, there is no guarantee that the coins listed on eBay are accurately graded per the standards of a major coin-grading service.

Still, there’s something to be said about using the eBay app to grade coins — because at least it gives you a broad range of actual coins out in the marketplace listed alongside the grades their sellers believe their coins to be.

If nothing else, it provides you with something of an education on what you might encounter when shopping for coins. It can offer as much as a lesson in coin grading as it can numismatic street smarts!

The eBay app is also terrific for buying and selling coins — something to keep in mind when you’re a coin collector!

The NGC App Shows How Rare Coins Are… In Every Grade

Another great app for finding out how rare your coins are is the NGC app by Numismatic Guaranty Company (NGC).

Like the PCGS CoinFacts app, the NGC app provides a coin census — showing how many coins the Numismatic Guaranty Company has graded at every grade level.

What’s the difference between a census (or population) and the mintage of a coin?

  • The mintage is an official record totaling how many examples of a certain coin the U.S. Mint struck.
  • The census (or population) is a tally of exactly how many coins have been accounted for by the agency reporting those figures.

In the case of the NGC census (like the PCGS population), this is simply a figure on how many coins these third-party coin graders have seen of a specific type at each grade level.

This is extremely helpful for getting an idea on how rare (or how common) a coin might be. But it’s important to keep in mind that people tend to submit more recent coins and those in lower grades less frequently than they do older coins and those in better condition.

The NGC app is an awesome tool that can help you find out more about your coins, their values, and other verifying information about coins graded by NGC!

The Greysheet Mobile App Shows How Much Coins Are Worth

So, you’ve graded your coins on the PCGS CoinFacts app, did some comparison coin grading on the eBay app, and used the NGC app to glean some more insight on how many coins have been slabbed at each grade.

Now what?

Now it’s time to find an app that will tell you how much your coins are worth at every grade!

One of the best coin pricing apps around is the Greysheet Mobile App.

Since 1963, Greysheet has been one of the leading market pricing guides for coin dealers. And now, thanks to the app, they provide coin prices and coin values for coin collectors, too!

Download the Greysheet coin app to find out what your coins are worth in a variety of grades.

The Bottom Line…

No matter what, when looking for an app to grade coins make sure you’re choosing one that comes from a reputable source.

PCGS and NGC are top names in the world of coin grading. Others are ANACS (formerly known as American Numismatic Association Certification Service), Independent Coin Graders (ICG), and Certified Acceptance Corporation Grading (CAG).

PCGS, NGC, ANACS, and ICG are known as the “Big Four” on the coin collecting scene. These are the 5 main third-party coin grading companies you can trust when submitting coins for certification or finding out more about coin grading.

That does not mean other companies aren’t trustworthy — but the 5 listed here are the most frequently used and they have been around the longest.

When you buy slabbed coins, you want to make sure they are from one of the 5 grading companies listed here.

    Good morning. I’m retired and needed something to do. So I started collection coins again. I found a 1943 zinc Penny with a defect. I have a problem with pricing. This has four impression, two on one side and two on the other side. They protrude from almost the center out to the edge and meet each other at the same location on dia of the coin. You can see the design shadow in the trench. So I would call it a planchette error. I have lots of 1943 zinc penny’s. Only one I have ever seen. What kind of price should I put on this coin.

      Hi, Richard!

      I’m glad you’ve returned to collecting coins! I’d love to please take a look at your 1943 cent so I can help further. Would you mind posting one or two clear photos of the coin here with the issues you’re asking about clearly visible so I can provide the best insight I can?

      Thank you,
      Josh

            Hi, Richard —

            It appears this 1943 steel penny has some heavy post-mint damage. These are two offset cut marks. Who’s to say how they got here in the last 80 years…

            Due to the fact there is no valuable precious-metal in this coin and the metals within are worth less than face value, this piece is essentially worth its face value. Though it’s nonetheless an interesting piece!

            Best wishes,
            Josh

      Hello, Richard —

      This is an interesting piece… One image shows a mint-caused anomaly and the others post-mint damage.

      The photo showing the date close up indicates your coin has some slight mechanical doubling. This is not an error or variety but rather a type of defect caused by worn dies and/or strike reverb. Machine doubling generally does not add any monetary value to a coin.

      The other interesting thing is the blatant lines or grooves on the edge of the coin. While they appear somewhat uniform, this is NOT an error caused at the mint. There are many ways someone could’ve imparted the appearance of edge reeding (which it is not!) on your coin, including by hand, by machinery, or by running/rolling the coin across a rigid grooved surface. At any rate, the grooves are post-mint damage and not derived from any part of the minting process.

      I can see why this coin was pulled from circulation though — it’s definitely a looker!

      Cheers,
      Josh
