While coin grading is a complex discipline that takes years of practice to fully master, one of the most useful tools for collectors of all levels is a coin grading chart. These visual guides provide a standardized frame of reference for evaluating a coin‘s wear, strike, luster, and overall eye appeal.
In this expert guide, we‘ll take a deep dive into the world of coin grading charts. We‘ll explore their origins and evolution, break down the most widely-used grading scales, and walk through a step-by-step process for evaluating your own coins. We‘ll also discuss the impact of grading on coin values, the role of professional grading services, and the latest trends shaping the future of coin grading.
Whether your goal is to build a high-value collection, become a more informed buyer, or maximize your profits when selling, a strong command of coin grading is a must. Let‘s get started!
The History and Importance of Coin Grading
Coin grading has a rich history dating back to the early days of numismatics in the 19th century. As the field of coin collecting grew and matured, collectors and dealers recognized the need for a standardized system to describe the condition of coins.
One of the earliest and most influential coin grading pioneers was Dr. William Sheldon, who introduced his 1-70 scale in 1949. The Sheldon Scale, as it came to be known, assigned numeric grades to coins based on their level of preservation, with "1" representing a virtually unidentifiable coin and "70" representing perfection.
Sheldon‘s scale brought much-needed consistency to coin grading, but it was not universally adopted overnight. In the decades that followed, various grading systems emerged, each with its own terminology and criteria.
It wasn‘t until the 1970s and 1980s that the field of coin grading truly standardized around the Sheldon Scale and the grading tiers used by the American Numismatic Association (ANA). The ANA‘s grading standards, which use terms like "Good," "Fine," and "Uncirculated," provide a more intuitive and accessible way for collectors to describe a coin‘s condition.
The rise of third-party grading services in the 1980s, led by the Professional Coin Grading Service (PCGS) and Numismatic Guaranty Corporation (NGC), marked another major milestone. By offering impartial, expert grading and encapsulation services, these companies brought a new level of confidence and liquidity to the coin market.
Today, coin grading is a cornerstone of numismatics. A coin‘s grade is one of the primary determinants of its market value, and a single point difference in grade can translate to thousands or even millions of dollars for the most coveted coins.
Consider some of these jaw-dropping sales:
-
In 2013, a 1794 Flowing Hair Silver Dollar graded PCGS SP-66 sold at auction for $10,016,875, setting a new world record for any coin.
-
An 1804 Draped Bust Dollar, one of only 15 known to exist, sold for $7.68 million in 2021. The coin‘s PCGS PR-65 grade was a key factor in its stunning price.
-
Even modern coins can command extraordinary premiums in top grades. In 2019, a 1999 Delaware State Quarter graded PCGS MS-68 sold for $5,640, more than 22,000 times its face value!
Of course, these are extreme examples featuring some of the rarest and most desirable coins. But they illustrate the incredible impact that grade has on a coin‘s ultimate value. For collectors at all levels, a solid grasp of grading fundamentals is indispensable.
The Two Key Coin Grading Scales
As mentioned, the two most widely-used coin grading standards today are the Sheldon Scale and the ANA Scale. While they use different terminology, they are largely equivalent in describing a coin‘s condition. Let‘s break them down:
The Sheldon Scale (1-70)
The Sheldon Scale assigns numeric grades from "1" to "70" based on a coin‘s level of preservation and visual appeal. Here‘s a simplified breakdown:
| Grade Range | Description |
|---|---|
| 1-59 | The coin shows signs of wear from circulation. Details are partially worn. |
| 60-70 | Uncirculated or "Mint State." No wear from circulation. |
Within the Mint State range, coins are further subdivided:
| Grade Range | Description |
|---|---|
| 60-62 | Mint State Basal. Visible marks or blemishes. |
| 63-64 | Mint State Choice. Minor imperfections. |
| 65-69 | Mint State Gem. Virtually flawless to the naked eye. |
| 70 | Perfect Uncirculated. No visible imperfections. |
The ANA Scale
The ANA grading scale uses a combination of qualitative grades and numeric sub-grades:
| Grade | Description |
|---|---|
| Poor (P) | Barely identifiable as to coin type. |
| Fair (F) | Heavily worn, but major design elements visible. |
| About Good (AG) | Heavily worn, but most lettering and major details visible. |
| Good (G) | Heavily worn, peripheral lettering nearly full. |
| Very Good (VG) | Design visible but lacking details. |
| Fine (F) | Moderate wear, all lettering sharp. |
| Very Fine (VF) | Light wear, details clear. |
| Extremely Fine (EF) | Slight wear only on high points. |
| About Uncirculated (AU) | No wear but may show slight imperfections. |
| Mint State (MS) | No wear, may range from dull to fully lustrous. |
It‘s important to note that while these scales provide a common language for describing coins, grading still involves a degree of subjectivity. Even professional graders may assign slightly different grades to the same coin based on their interpretation of its strike, luster, toning, and overall eye appeal.
This is why many collectors recommend buying the coin, not the grade. A coin with an appealing look and originality for its assigned grade is generally more desirable than a "barely there" example of the next highest grade.
Coin Grading in Practice: How to Use a Grading Chart
Now that we‘ve laid the conceptual groundwork, let‘s get practical. How do you actually use a coin grading chart to assess your own coins? Here‘s a step-by-step guide.
Step 1: Gather Your Tools
To properly evaluate a coin, you‘ll need:
- A coin grading chart with high-resolution images and descriptions for each grade
- A high-quality magnifying glass (5-10x power) or loupe
- Protective gloves for handling the coin
- A well-lit workspace, ideally with a desk lamp
Step 2: Examine the Coin‘s Surfaces
Put on your gloves and pick up the coin, holding it under the light. Rotate it slowly, examining every part of the surface on both the obverse (front) and reverse (back).
Here‘s what to look for:
-
Wear: Look for flattening or loss of detail on the high points of the design, like the cheek and hair on a portrait coin. The degree of wear is the primary determinant of a coin‘s grade.
-
Luster: This is the natural sheen that freshly-minted coins have. Uncirculated coins will have full luster, while circulated coins may have little or none.
-
Marks: Note any scratches, nicks, or dings on the surface. The size, number, and location of marks can significantly impact the grade.
-
Eye Appeal: Take a step back and consider the coin‘s overall appearance. Is it attractive and original-looking for its grade, or does it have distracting blemishes or an unnatural color?
Step 3: Compare to the Grading Chart
With your magnifying glass in hand, start comparing your coin to the images on the grading chart. Pay special attention to the amount of wear, luster, and marks.
Here are a few tips:
-
Start with the high points of the design. If they‘re worn flat, the coin is likely in the Good to Very Good range.
-
If the high points show only slight wear and the coin retains significant luster, it may be in the Extremely Fine to About Uncirculated range.
-
A coin with full luster, sharp details, and minimal marks may grade Mint State. Use the chart images to narrow down the numeric grade.
-
When in doubt, assign a slightly lower grade. It‘s better to be conservative than to overstate the coin‘s condition.
Step 4: Consider Professional Grading
For valuable or rare coins, most serious collectors and dealers will opt for professional third-party grading by PCGS, NGC, or another reputable service.
The benefits of professional grading include:
- An impartial, expert assessment of the coin‘s condition
- Consistent grading standards and a guarantee of authenticity
- A protective plastic holder that encapsulates the coin
- Easier marketability and often a premium when selling
Professional grading isn‘t cheap – expect to pay $30-$300 or more per coin depending on its value. But for important coins, the benefits can far outweigh the cost.
Coin Values and the Impact of Grade
With a solid understanding of how to grade coins, let‘s dive deeper into how grade influences a coin‘s value on the market.
Grading and Value: Key Principles
Coin values depend on several factors, but grade is one of the most significant. Here are some key concepts:
-
Rarity: In general, the rarer a coin is at a given grade level, the more valuable it will be. A common coin in pristine condition may be worth less than a scarce coin in average condition.
-
Series Popularity: Certain coin series, like Morgan Dollars or Saint-Gaudens Double Eagles, are especially popular with collectors. Grades being equal, coins from these series will often sell for a premium.
-
Strike and Eye Appeal: Two coins at the same numeric grade can still vary in value based on their visual qualities. A well-struck coin with attractive toning will command higher prices than a softly-struck coin or one with distracting blemishes.
Grade vs. Value: An Example
To illustrate the dramatic effect of grade on value, let‘s look at a specific coin series – the Lincoln Wheat Cent.
| Grade | 1909-S VDB | 1914-D | 1922 No D |
|---|---|---|---|
| Good-4 | $700 | $250 | $600 |
| EF-40 | $1500 | $400 | $1100 |
| MS-63RB | $2500 | $550 | $3000 |
| MS-66RD | $5000 | $1500 | $20,000 |
(Approximate retail values based on recent auction results and price guide data. Actual prices may vary based on market conditions.)
As you can see, the same coin can be worth many times more in Mint State than in circulated condition. The jump is especially pronounced for key dates like the 1909-S VDB and 1922 No D.
Of course, these are just a few examples from one series. The same principle applies across all U.S. and world coins – grade has an outsized impact on market value, and small differences in grade can translate to large differences in price. This is why it pays to sharpen your grading skills!
The Future of Coin Grading
As we‘ve seen, coin grading has evolved significantly over the past century and a half. But where is it headed in the coming decades? Here are a few key trends and developments to watch:
-
Digital Imaging: High-resolution digital photography and 3D scanning are making it easier than ever to examine coins remotely. While there‘s no substitute for in-hand grading, these technologies are a valuable supplement.
-
AI-Assisted Grading: Several companies are working on artificial intelligence systems that can analyze digital images of coins and assign grades. While still in the early stages, AI could eventually provide a "first pass" grade to help speed up the human grading process.
-
Refinements to Grading Standards: As the field of numismatics evolves, so too do grading standards. Organizations like PCGS and NGC continually refine their grading criteria and introduce new designations like "Full Bands" or "Plus" grades to capture finer distinctions in quality.
-
The Rise of Modern Coin Collecting: While classic series like Wheat Cents and Morgan Dollars still dominate the market, modern coins are gaining in popularity. Collectors are increasingly seeking out high-grade examples of more recent issues, driving up prices and interest in modern grading.
Whatever the future holds, one thing is certain – the ability to accurately grade coins will remain a critical skill for collectors and dealers alike. By staying up to date on grading standards and best practices, numismatists can position themselves for success in the ever-evolving coin market.
Grading Gems: Tips from the Experts
To wrap up our deep dive into coin grading, here are some words of wisdom from a few of the hobby‘s leading lights:
"Buy the coin, not the holder. A coin‘s grade is important, but it‘s not the only factor. Look for coins that are attractive and original for their grade – they‘ll be the most desirable in the long run."
– John Albanese, Founder of Certified Acceptance Corporation (CAC)
"Grading is a skill that takes years to master. Start by focusing on a single series that interests you, and study as many coins as you can. Over time, you‘ll develop a keen eye for the subtleties that separate one grade from another."
– Mark Salzberg, Chairman of Numismatic Guaranty Corporation (NGC)
"Don‘t get too caught up in chasing perfection. A well-matched set of coins in mid-range circulated grades can be just as satisfying to own as a single ultra-high-grade rarity. Collect what you love and enjoy the journey."
– Q. David Bowers, Noted Numismatic Author and Scholar
With these insights in mind, you‘re well on your way to becoming a skilled grader and savvy collector. Remember – coin grading is a lifelong pursuit, and there‘s always more to learn. But with a solid foundation in the basics and a commitment to ongoing study, you‘ll be well-equipped to navigate the exciting world of numismatics. Happy hunting!
