The Sheldon Coin Grading Scale is the foundation of modern numismatics, standardizing how collectors and dealers assess coin grades. Created by Dr. William Herbert Sheldon in 1949, this grading system ranges from P-1 (Poor) to MS-70 (Perfect Mint State).
It assigns a numerical grade based on factors like a coin’s condition, eye appeal, and luster, providing consistency in evaluating rare and historic coins.

Let's explore the Sheldon scale and its role in numismatics in greater detail.
Before the Sheldon coin grading scale was developed, inconsistencies in coin grading created confusion and disagreements among collectors and dealers. Grading lacked a standardized method, leaving the value of rare coins open to subjective interpretation.
Dr. William Herbert Sheldon revolutionized numismatics with the introduction of the Sheldon coin grading scale in 1949, initially designed to evaluate 18th-century large cents.
This groundbreaking system assigned numerical grades based on a coin’s condition and linked these grades to its market value, with Poor (P-1) being the lowest and Mint State (MS-70) the highest.
For the first time, the Sheldon coin grading scale brought uniformity to a field previously dominated by subjective appraisals.
By assigning a numerical grade to every coin, the grading scale streamlined transactions between collectors and coin dealers. This standardization has been especially helpful in simplifying the buying, selling, and appraisal of rare coins, allowing both novice and experienced numismatists to conduct transactions with confidence.
Today, third-party grading services such as the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Company (NGC) widely use variations of Sheldon’s original scale to maintain consistency across the industry.
The original Sheldon scale focused on large copper cents, but its utility quickly expanded to include all coins of the United States dollar and even international issues.
For instance, mint state coins with no visible wear retained higher grades, while circulated coins showed signs of wear that reduced their condition score.
The Sheldon scale evaluates coins on a scale of 1 to 70, representing their condition and rarity.
A P-1 coin is heavily worn with very little detail remaining, while an MS-70 coin showcases a flawless, uncirculated state with perfect mint luster and no visible imperfections. Each grade between these extremes reflects specific characteristics:
| Grade Range | Name / Classification | Definition & Eye Appeal |
|---|---|---|
| P1–FR2 | Poor (P–1) to Fair (FR–2) | Coins are barely identifiable, with heavy flattening of design and major features worn smooth. Date and mintmark may be partially or wholly illegible; surfaces are heavily scratched or damaged. |
| G4–G6 | Good (G–4 to G–6) | Design outlines remain but show extreme even wear; rims may merge into fields. Major elements (profile, shield, etc.) are visible only in outline form, with legends and date weak but readable. |
| VG8–VG10 | Very Good (VG–8 to VG–10) | Moderate to heavy wear leaves major devices well outlined, with some secondary details visible in protected areas. Lettering and date are clear; rims are complete though flattened. |
| F12–F15 | Fine (F–12 to F–15) | 34 billion+ minted; only high‑grade or error pieces carry premiums. |
| VF20–VF35 | Very Fine (VF–20 to VF–35) | Light to moderate wear on high points; most major and secondary details are clear. Some original luster may survive in protected areas, with hairlines and scrollwork showing moderate definition. |
| XF40–XF45 | Extremely Fine (EF/XF–40 to 45) | Minor wear confined to the highest points; full detail in mid- and low-relief areas. Original mint luster is evident in protected recesses; contact marks are minimal. |
| AU50–AU58 | Almost Uncirculated (AU–50 to 58) | Trace wear on only the very highest points; at least half of the original luster remains across most of the surface. Excellent eye appeal, with only slight friction on devices. |
| MS60–MS62 | MS-60 to MS-62 (BU) | Uncirculated coins with full mint luster but numerous contact marks, hairlines, or weak strikes. Brilliant surfaces may appear impaired by bag friction or minting defects. |
| MS-63 | Choice BU | Uncirculated coins with average to above-average eye appeal, fewer distractions than lower MS grades. Attractive luster and strike; contact marks are present but not overly distracting. |
| MS-64 | Select BU | Uncirculated coins with above-average overall quality and only moderate contact marks or abrasions. Strong luster and strike; any marks are minor and do not detract significantly. |
| MS-65 | Gem BU | Uncirculated coins exhibiting superior quality, with only minimal contact marks confined to the highest points. Highly attractive surfaces with exceptional luster—considered “gem” quality. |
| MS-66 to MS-67 | Superb BU | Uncirculated coins with very few minor contact marks; luster remains full and vibrant. Premium surfaces that stand out even under close inspection; only slight imperfections are visible. |
| MS-68 to MS-69 | Superb Brilliant BU | Near-flawless uncirculated coins with virtually no contact marks and breathtaking luster. Exemplary brilliance and strike; any blemishes are microscopic and barely detectable. |
| MS-70 | Perfect | The pinnacle of the Sheldon Scale—no post-production imperfections at 5× magnification. Absolutely pristine surfaces, full luster, and a razor-sharp strike—exceedingly rare and highly prized by collectors and investors alike. |
Knowing a coin's grade is essential for both seasoned numismatists and beginners. An accurate evaluation determines the market value and authenticity of your collection. The Sheldon scale provides a universal system for assigning grades, ensuring clarity when buying, selling, or appraising coins. Rare coins with higher numerical grades, such as uncirculated Mint State coins, often fetch significantly higher market prices than circulated examples.
Achieving an accurate coin grade requires careful assessment of multiple attributes.
These factors serve as universal benchmarks, ensuring that coins are graded consistently across all levels of expertise. Collectors and dealers frequently evaluate these elements to distinguish circulated coins from uncirculated coins and assign appropriate values.
One of the most critical aspects of any coin’s grade is its luster, which refers to how light reflects off the coin’s surface. A well-preserved coin has an even sheen that often signifies originality and minimal handling.
If mint luster remains intact, collectors can be confident that the coin hasn't been cleaned or overhandled. Using magnification tools like a loupe, you can examine the surface for dulling or uneven reflections, which may indicate cleaning or improper storage.
For professional grading services, surface preservation and strike are equally important. Surface preservation involves evaluating contact marks, scratches, or other imperfections caused by contact with other coins.
The strike indicates how well the coin’s design was impressed during minting, with sharp, clear designs being a hallmark of higher grades. For example, proof coins and early United States Mint issues often have sharper details, distinguishing them as fine examples of their type.
Wear is one of the most visible factors affecting a coin’s grade and value, making its detection a fundamental skill for any numismatist. Wear typically appears first on the highest points of a coin, where natural handling or circulation gradually erodes fine details.
On United States coins, features such as Liberty’s hair or eagle feathers are commonly examined for signs of wear. These areas often lose detail long before the rest of the coin’s design shows noticeable degradation, directly influencing its numerical grade on the Sheldon Coin Grading Scale.
Eye appeal is the “wow” factor that elevates a coin beyond its technical grade—encompassing surface brilliance, color (toning), and the presence—or absence—of contact marks. Even two coins with identical scores can command very different premiums: the one with vibrant luster, harmonious toning, and clean fields will always outshine a dull or heavily nicked counterpart. In professional grading, eye appeal often distinguishes a merely “correct” grade from a truly collectible coin, directly impacting market demand and resale value.
When assessing a coin’s grade, focus on the highest points of the coin, as these areas receive the most wear during circulation. A close examination under magnification will help identify subtle contact marks or trace amounts of wear that could lower the coin’s condition. Look for coins with swirly luster and strong eye appeal to draw the highest grading scores.
By understanding these grading factors, both novice and experienced collectors can appreciate the intricacies of coin grading and make informed decisions during their numismatic journey.
Many collectors are curious about what elevates a coin grade to a premium level. The Sheldon Coin Grading Scale, originally developed by William Herbert Sheldon, evaluates key features such as surface condition, strike quality, and luster.
Coins with these attributes in optimal condition are highly sought after by numismatists, especially those who understand the distinction between circulated and uncirculated grades.
For a coin to earn a higher grade, its overall condition must demonstrate exceptional sharpness in its strike and preservation. Subtle details like the high points of a coin’s design must remain intact. Coins showing no signs of wear or cleaning retain their original appeal and value, which collectors assess under magnification to detect imperfections such as contact marks.
Inspecting a coin’s luster under proper lighting is another critical practice. The iconic “cartwheel effect” often signals a well-preserved mint state coin.
Evaluating edge lettering, rim integrity, and even the clarity of the coin's design ensures that collectors can identify coins with significant potential for premium grades. With an emphasis on these features, buyers can make informed decisions, whether at auctions, coin shows, or trusted local numismatic dealers.
Third-party grading transforms the way collectors evaluate rare coins. By relying on services like the Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC), coin collectors gain access to an objective and standardized assessment of a coin's quality.
These services thoroughly examine the
coin and assign a
grade based on industry-standard benchmarks, such as the
Sheldon Coin Grading Scale. This method eliminates subjectivity, ensuring a more transparent process for buyers and sellers alike.
For those who seek to protect the value of their collection, professional
coin grading is a trusted option. For example, when a
coin grading service authenticates your
mint state or
proof coins, it significantly boosts buyer confidence. This is particularly important for
coins struck with historical relevance or high monetary value. The resulting certification provides a tamper-proof guarantee of the
grade and condition, offering collectors peace of mind when investing in rare and
numismatic items.
Third-party grading becomes indispensable when attempting to assign an accurate value to
coins that exhibit unique physical traits or rare
eye appeal. For example, a certified
uncirculated coin with minimal
wear is instantly more marketable than a similar ungraded piece.
