The Sheldon Coin Grading Scale is a 70-point coin grading scale used in the numismatic assessment of a coin's quality. The American Numismatic Association based its Official ANA Grading Standards in large part on the Sheldon scale. The scale was created by William Herbert Sheldon.
Original Sheldon Scale (1949)
In 1949, the original scale was first presented in Dr. William H. Sheldon's Early American Cents, 1793–1814 titled "A Quantitative Scale for condition" as a way to grade large cents. The scale is known today as the Sheldon scale.

Adapted scale (1970s–present)
By 1953 the original Sheldon scale had become outdated. It was not until the 1970s, however, that the ANA chose to adapt the scale for use on all US coins. The scale used today is a modification of the original Sheldon scale, with added adjustments, additions, deletions, and modifications to it.
Note: Some early American coin varieties are almost always found to be weakly struck in places. This does not bring the grade of these coins down as in some cases no flawless coin exists for the variety. Early coins in general usually have planchet quality issues which depending on severity and market conditions can bring the grade down for other coins.

# Grade Grade code(s) Description 1 Poor PO Clear enough to identify, date may be worn smooth with one side of the coin blanked. Coins that are very badly corroded may also fall under this category. 2 Fair FR Some detail shows 3 About Good AG Readable lettering although very heavily worn. The date and design may be worn smooth. 4 Good G, G4 Rims of the coin are slightly worn, design is visible, but faint in areas, with many parts of the coin worn flat. Peripheral lettering nearly full. 6 Choice Good G+, G6 Rims of the coin are complete. Peripheral lettering is full. 8 Very Good VG, VG8 Slight detail shows, with two to three letters of the word LIBERTY showing in coins with this feature. 10 Choice Very Good VG+, VG10 Slightly clearer design-features, with five or possibly six letters of the word LIBERTY showing in coins with this feature. 12 Fine F, F12 Some deeply recessed areas show detail.

Uncirculated grades
Mint State refers to a coin minted for regular distribution that was never actually put into circulation, i.e., it was never used for daily commerce; it is uncirculated. Since individuals never used these coins to purchase goods or services, the coins were not handed from one person to another; they were not jumbled up with other coins in pockets or purses; and they were not repeatedly counted—and touched—by retailers and bank personnel. Consequently, uncirculated coins should not show signs of wear.
In modern-day United States numismatics, collectors, coin dealers, and third-party grading services grade mint state coins using a number from 60 to 70 inclusive, with 70 representing a perfect coin with no visible blemishes. Coins in the lower grade range (60-63), are usually unworn, and may suffer from weak striking, bag marks and other defects that make them less attractive to the collector. Some Mint State early coins appear to be circulated due to weak strikes, die cracks, planchet problems, or metal quality. There are a few United States coins for which no mint state specimens exist, such as the 1792 silver dime, and the 1802 Draped Bust (Heraldic Eagle reverse) silver half dime.
Adjectival grades for uncirculated coins Coin dealers and individual coin collectors often use adjectives—with or without an accompanying Sheldon numerical grade—to describe an uncirculated coin's grade. The term Brilliant Uncirculated (often abbreviated as BU) is probably the most common—and the most ambiguous—of such adjectives. While Brilliant Uncirculated (BU) ought to refer to an uncirculated coin that retains its original mint luster, some equate BU with Uncirculated, i.e., they might refer to an MS-60 coin with little or no effulgence (brightness) as Brilliant Uncirculated. Along these lines, some numismatists argue that an unscrupulous subset of coin dealers mislead customers by using adjectival grades without defining their terms. At the same time, there appears to be at least some consensus in the numismatic community for the following definitions. +Commonly Used (but unofficial) Adjectival GradesAdjectival GradeEquivalent Numerical GradeUncirculatedMS-60, MS-61, MS-62Select or Choice UncirculatedMS-63Choice UncirculatedMS-63, MS-64Gem UncirculatedMS-65, MS-66Superb Gem UncirculatedMS-67, MS-68, MS-69Perfect UncirculatedMS-70 However, bear in mind that if a coin dealer advertises a coin as "Gem Uncirculated", it does not necessarily mean that a third-party coin grading company would assign an MS-65 or MS-66 grade to the coin.
Numerical grades for uncirculated coins # Grade Grade code Description 60 Mint State 60 MS60 Unattractive, dull or washed-out, mint luster typify this coin. There may be many large detracting contact marks (bag nicks), or damage spots, but absolutely no trace of wear. There could be a heavy concentration of hairlines (minute scratches to a coin's surface), or unattractive large areas of scuff-marks. Rim nicks may be present, and eye appeal is very poor. Copper coins may be dark, dull and spotted. 61 Mint State 61 MS61 Mint luster may be diminished or noticeably impaired, and the surface has clusters of small contact marks throughout. Hairlines could be very noticeable. Scuff-marks may show as unattractive patches on large areas or major features. Small rim nicks, striking or planchet defects may show, and the quality may be noticeably poor. Eye appeal is unattractive. Copper pieces will be generally dull, dark and possibly spotted. 62 Mint State 62 MS62 Impaired or dull luster may be evident. Clusters of small marks may be present throughout with a few large marks or bag nicks in prime focal areas. Hairlines may be very noticeable. Large unattractive scuff-marks might be seen on major features. The strike, rim and planchet quality may be noticeably below average. Overall eye-appeal is generally acceptable. Copper coins will show a diminished color and tone. 63 Mint State 63 MS63 Mint luster may be slightly impaired. Numerous small contact marks, and a few scattered, heavy marks may be seen. Small hairlines are visible without magnification. Several detracting scuff marks or defects may be present throughout the design or in the fields. The general quality is average, but overall, the coin is rather attractive. Copper pieces may be darkened or dull. 64 Mint State 64 MS64 Coin has good, overall average luster and even strike for the type. Several small contact marks in groups, as well as one or two moderately heavy marks may be present. One or two small patches of hairlines may show under low, (3-4x) magnification. Noticeable, light, scuff marks or defects may be seen within the design or in the field. Attractive overall quality with a pleasing eye appeal. Copper coins may be slightly dull. 65 Mint State 65 MS65 Coin shows an attractive high quality of luster and strike for the date and originating mint. A few, small, scattered, contact marks, or two larger marks may be present, and one or two small patches of hairlines may show under (5x+) magnification. Noticeable, light, scuff marks may show on the highest points of the design features. Overall quality is above average and eye appeal is very pleasing. Copper coins have full luster with original or darkened color. 66 Mint State 66 MS66 Coin has above average quality of strike and full original mint luster, with no more than two or three minor, but noticeable, contact marks. A few very light hairlines may show under (6x+) magnification, or there may be one or two light, scuff marks showing on frosted surfaces or in the field. The eye appeal must be above average and very pleasing for the date and originating mint. Copper coins display full original or lightly toned color. 67 Mint State 67 MS67 Coin has a sharp strike with full, original luster, May have three or four very small contact marks and a single, more noticeable, but not detracting mark. On comparable coins, one or two small single hairlines may show under (6x+) magnification, or one or two partially hidden scuff marks or flaws may be present. Eye appeal is exceptional. Copper coins have lustrous original color. 68 Mint State 68 MS68 Coin has a sharp strike with full original luster, with no more than four, lightly-scattered, contact marks or flaws. No hairlines or scuff marks show. Copper coins have lustrous original color. Eye appeal is exceptional. 69 Mint State 69 MS69 Coin has a sharp strike with full original luster, with no more than two small non-detracting contact marks or flaws. No hairlines or scuff marks are visible. Eye appeal is exceptional. 70 Mint State 70 MS70 The "perfect coin", as minted. Has no trace of wear, handling, scratches or contact with other coins from a (5x) magnification. Coins in this grade are almost non-existent in older coins with very few examples known. Copper coins are bright with full original color and luster. Eye appeal is exceptional.
Proof coins
Like circulated grades, proof coins are graded on the Sheldon scale from 1 to 70, and are preceded by the abbreviation ‘PF’ or ‘PR’ to distinguish them from circulation strikes. Proof coins graded 60 to 70 are mirrored to those of Uncirculated grades with the difference that the coin was not made for circulation. Proof coins with the grade of PR-63 are sometimes called "Choice Proofs". Proof coins that are below the grade of 60 and show signs of circulation or mishandling have been classified as Impaired Proofs, these are not included alongside circulated coins as they were never issued or intended for circulation in the first place. Coins in impaired proof condition include coin patterns which accidentally found their way into circulation.
