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 left up to professional coin graders, like PCGS (Professional Coin Grading Service).

For example, here’s a 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

This is the OFFICIAL American Numismatic Association Grading Standards book for U.S. coins.

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. 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 the list of coin grades and what they mean:

  • Proof-70 = Perfect Proof
  • Proof-65 = Choice Proof
  • Proof-60 = Proof
  • MS-70 = Perfect Uncirculated
  • MS-65 = Choice Uncirculated
  • MS-60 = Uncirculated
  • AU-55 = Choice About Uncirculated
  • AU-50 = About Uncirculated
  • EF-45 = Choice Extremely Fine
  • EF-40 = Extremely Fine
  • VF-30 = Choice Very Fine
  • VF-20 = Very Fine
  • F-12 = Fine
  • VG-8 = Very Good
  • G-4 = Good
  • AG-3 = About Good

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:

Proof-70: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:Under a magnifier will show only very fine hairlines on the coin.
Proof-60:A proof coin with scattered hairlines and handling marks that can be seen even without a magnifying tool.
MS-70:A non-proof coin that contains no lines, bag marks, or anything of the sort. A perfect coin.
MS-65:Scattered bag marks on the surface, or one or two very light rim marks.
MS-60:Uncirculated coin with a moderate number of bag marks. May have a few minor edge nicks and marks.
AU-55: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:Traces of wear on nearly all of the highest points. Must still have at least half of the mint luster present.
EF-45:Light overall wear on the highest points. Mint luster only in protected areas — such as in between stars and letter spacing.
EF-40:Still only having slight wear, but a little more extensive than the preceding grade. Design still has excellent sharpness.
VF-30:Light, even wear on the surface. Design details on the highest points lightly worn, but all lettering and major features sharp.
VF-20:Same as the preceding grade, except with moderate wear on the high points.
F-12:Moderate to considerable even wear. Entire design is bold. All lettering is visible but with some weakness.
VG-8:Well worn. Most fine details such as hair strands, leaf details, and so on are worn nearly smooth.
G-4:Heavily worn. Outside outlines of design are visible, but center detail of the design is worn smooth.
AG-3: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 have compiled some coin grading notes for each denomination of U.S. coins — so you’ll know exactly what to look for:

Grab a coin magnifier and a copy of the U.S. Coin Grading Standards book. Then, watch this video to see how to grade coins yourself at home:

How To Grade A Coin Yourself To Determine Its Value

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.

  1. i have couple questions on some pennys that i found the first one is about a 1964 D penny that on the front instead of having the word LIBERTY has BERTY only.. and the other one is a 2012 penny that has this rare caramel color it’s just way diferent from all the rest .. what do i do ?

    • Hi, Mondo –

      Hmm, if you wouldn’t mind posting a picture of the both coins here, it would help greatly. Thanks!

    • HI, John —

      The “V” isn’t from the Mint, but rather it is a counterstamp from a post-mint company or individual. If the origin of the “V” could be traced, it could actually help to raise the value of the coin beyond its usual 5 cents, even though the “V” is an alteration.

      Could “V” stand for a company name? “V” for World War II victory? Who knows… If only coins could talk, right?

      Thank you for your question and photo,

    • Hi, Chris —

      It’s a well-worn one, but this 1943 steel cent is worth about 7 to 10 cents… Personally, I hang on to all of these well-worn wheat cents, steel and copper, that come my way. I’d suggest the same for you, too.

      Thank you for your question and photo,

    • Hello, Ever —

      This 1944-D Lincoln cent is worth a small premium of about 5 cents. It’s still a neat coin to hold on to — it’s a World War II-era relic, as it was made from copper recovered from spent copper shell casings.

      Cool find,
