How Is Rare Coin Grading Determined?
Rare coin grading evaluates several key factors. This process assesses a coin’s condition, authenticity, and overall quality. Both circulated and uncirculated coins undergo this meticulous evaluation.
Grading Scales
The Sheldon Coin Grading Scale is the most widely used system for rare coin grades. This 70-point scale, developed by Dr. William Sheldon in 1949, ranges from 1 (Poor) to 70 (Perfect Mint State). A score of MS-70 indicates a coin in perfect uncirculated condition.
Categories of Grades
- Circulated Coins: These coins show wear and are graded from Poor (P-1) to Very Fine (VF-20). Different grades within this range include Good (G-4), Very Good (VG-8), Fine (F-12), and Very Fine (VF-20).
- Uncirculated Coins: These coins lack wear and are graded from MS-60 to MS-70. For example, MS-60 describes an uncirculated coin with possible heavy marks and dull luster, while MS-65 describes a coin with few marks and no significant imperfections.
Factors Considered in Grading
Grading rare coins involves evaluating several critical factors:
- Mint Luster: The original shine of the coin.
- Strike: The quality of the coin’s imprint.
- Wear: The extent of surface abrasion.

Sheldon Grading Scale: Understanding Coin Grades
The Sheldon Grading Scale, developed by Dr. William Herbert Sheldon in 1949, provides a detailed system for evaluating and describing the condition of rare coins. It facilitates informed investment decisions and enhances appreciation for coin collection.
(P-1) Poor
Coins in this grade are very badly worn. The date might be worn smooth, and one side may be blanked. They are often heavily corroded.
(FR-2) Fair
Fair coins show some visible details but most of the coin is worn flat on both sides. They are in slightly better condition than Poor but still exhibit significant wear.
(G-4) Good
Good grade coins have a design that’s faint or worn in certain areas. Rims are slightly worn, and peripheral lettering is almost complete. While the coin shows clear signs of wear, it remains recognizable.
(VG-8) Very Good
Very Good coins show well-worn surfaces. Main features are clear and bold, though somewhat flat. While worn, these coins maintain a distinct appearance.
(F-12) Fine
Fine coins exhibit moderate to considerable even wear. The entire design is bold and presents an overall pleasing appearance. Their clarity and detail make them desirable among collectors.
(VF-20) Very Fine
Very Fine coins show light to moderate wear, with all major details visible. High points are lightly worn, and finer details still present, improving their collectibility.
(EF-40) Extremely Fine
Coins graded Extremely Fine display only minor wear on high points. Details are sharp, though minimal wear might be apparent. They retain a significant portion of their original mint luster.
(AU-50) About Uncirculated
About Uncirculated coins have slight traces of wear on high points. Virtually all of the original mint luster is present, with only the smallest signs of handling visible.
(AU-58) Very Choice About Uncirculated
These coins are almost uncirculated but may show traces of wear on only the highest points. Mint luster remains nearly complete, making them attractive to collectors.
(MS-60) Mint State Basal
Mint State Basal coins exhibit no wear but may have noticeable contact marks, strike weakness, or unattractive toning. They are uncirculated but lack the aesthetic appeal of higher mint grades.
(MS-63) Mint State Acceptable
These coins are uncirculated with acceptable luster and few contact marks or blemishes. They possess finer detail and eye appeal than MS-60 coins, making them more desirable.
(MS-65) Mint State Choice
Mint State Choice coins are well-struck and have strong luster. They exhibit very few contact marks or blemishes, presenting an attractive appearance. Collectors highly value them for their quality.
(MS-68) Mint State Premium Quality
Coins in this category are nearly flawless with exceptional luster and sharp strike. They have very few, if any, contact marks, making them highly collectible and valuable.
(MS-69) Mint State Almost Perfect
These coins are nearly perfect, with minuscule imperfections barely visible under magnification. They exhibit excellence in strike and luster, ranking just below perfect in the Sheldon Scale.
(MS-70) Mint State Perfect
Mint State Perfect coins show no post-production imperfections visible under 5x magnification. Their flawless appearance and exceptional quality make them the highest grade in the Sheldon Scale. Collectors often seek them out for their unparalleled quality and rarity.
Understanding these grades offers insight into the standards used by PCGS and NGC for rare coin evaluation, helping collectors better navigate and value their acquisitions.
