Most coin collectors want to be able to look at their coins and determine at least an “approximate” grade for each of them — because a coin’s grade is the first step in determining a coin’s value.
I might as well tell you now that you’re not always going to be super accurate when grading coins yourself (especially if you’re just beginning to collect coins) — but you CAN get a good grasp on what types of “wear” to look for and start determining coin grades on your own at home!
Being able to grade a coin accurately comes from a lot of experience. It’s usually best left to coin graders like Professional Coin Grading Service (PCGS) to professionally determine the condition and grade of your coins. When they’re done, they’ll encase your graded coin in a protective case — see picture below.
Here’s everything you want to know about slabbed coins.
This is a good “visual summary” of the different coin grades from the PCGS:
It’s not always easy to tell the difference between each grade — especially when you only have one example of that coin in your hands.
That’s where a coin grading book comes in handy…
How U.S. Coins Are Graded
Coins are most widely graded using the ANA (American Numismatic Association) Grading Standards. Therefore, the best book to use as a guide when you’re grading coins at home is this one.
If you view what a coin is worth in any type of coin price guide, they are using the ANA grading system.
Any coin can be graded using ANA’s guidelines — from the oldest obsolete coins to coins still in production today.
How A Coin’s Design Affects Its Grade
A coin’s design always has certain vulnerable areas:
- Some parts of the design are more highly raised than others and will show wear the quickest.
- Some of the engraved lines are shallower than others and will wear away more quickly from day-to-day handling.
By carefully examining a coin and checking these vulnerable areas, you can determine if a coin is circulated or uncirculated. If a coin is circulated, then its vulnerable areas can also establish a specific grade by the amount of wear that they’ve absorbed.
When grading coins (especially if they’re your coins), you have to stick to the strict guidelines. You can’t say, “Well my coin’s just half of a hair away from being MS-60 so I’ll grade it MS-60.” A lot of times, a coin in MS-60 condition can be worth 200% more than if it were given one grade lower — which is why it’s important to grade them accurately, even if they’re your own coins.
Many sellers do this nowadays, trying to make more money for their coins. They’re betting that the buyer won’t be able to tell that slight difference and pay for a grade that they’re not actually receiving. This is called slider grading… stay away from it.
Coin Grade Abbreviations
Using the ANA coin grading system, there are standards for every type of coin. This article just covers the basics — but we talk about grading individual types of coins at length in other articles.
To begin grading coins, you’ll need to know the grades and their abbreviations.
Here is a list of coin grades and what they mean:
What Coin Grade Abbreviations Really Mean
To give you a better (but not exact) way to grade your coin, here is what these words really mean:
| Grade | Meaning | Definition |
|---|---|---|
| Proof-70 | Perfect Proof | A coin with no hairlines, handling marks, or defects whatsoever. In other words, a perfect coin through and through. The coin can be brilliant or have natural toning. |
| Proof-65 | Choice Proof | Under a magnifier will show only very fine hairlines on the coin. |
| Proof-60 | Proof | A proof coin with scattered hairlines and handling marks that can be seen even without a magnifying tool. |
| MS-70 | Perfect Uncirculated | A non-proof coin that contains no lines, bag marks, or anything of the sort. A perfect coin. |
| MS-65 | Choice Uncirculated | Scattered bag marks on the surface, or one or two very light rim marks. |
| MS-60 | Uncirculated | Uncirculated coin with a moderate number of bag marks. May have a few minor edge nicks and marks. |
| AU-55 | Choice About Uncirculated | Coin that was in circulation only for a very brief period of time. Only shows a small trace of wear on the highest points. |
| AU-50 | About Uncirculated | Traces of wear on nearly all of the highest points. Must still have at least half of the mint luster present. |
| EF-45 | Choice Extremely Fine | Light overall wear on the highest points. Mint luster only in protected areas — such as in between stars and letter spacing. |
| EF-40 | Extremely Fine | Still only having slight wear, but a little more extensive than the preceding grade. Design still has excellent sharpness. |
| VF-30 | Choice Very Fine | Light, even wear on the surface. Design details on the highest points lightly worn, but all lettering and major features sharp. |
| VF-20 | Very Fine | Same as the preceding grade, except with moderate wear on the high points. |
| F-12 | Fine | Moderate to considerable even wear. Entire design is bold. All lettering is visible but with some weakness. |
| VG-8 | Very Good | Well worn. Most fine details such as hair strands, leaf details, and so on are worn nearly smooth. |
| G-4 | Good | Heavily worn. Outside outlines of design are visible, but center detail of the design is worn smooth. |
| AG-3 | About Good | Very heavily worn with portions of the lettering, date, and legends being worn smooth. Date is barely readable. |
How To Grade A Coin Yourself
Keep in mind, the exact descriptions of circulated grades vary greatly for each type of coin.
That’s why it is essential to refer to the specific grading text of the exact type of coin you are wanting to grade.
For example:
- On a Mercury dime you will look to see if the lines on the columns on the reverse side of the coin are visible.
- On a Morgan silver dollar you will look at the reverse and see if the lines in the eagles feathers are clear.
Since there are many many types of coins, no single article could cover all of them. I’ve compiled some coin grading notes for each denomination of U.S. coins — so you’ll know exactly what to look for:
- How To Grade Silver Dollars
- How To Grade Half Dollars
- How To Grade Quarters
- How To Grade Dimes
- How To Grade Nickels
- How To Grade Pennies

Okay, that should give you plenty to look at — so you can get at least some idea of your coin’s grade.
Hopefully, now you should have a better idea as to your coin’s worth, as well.
