Professionally graded coins are assigned a number from 1 to 70, which corresponds to the Sheldon Scale. This universally accepted grading system was designed on the premise that a coin with a rating of 70 would be worth 70 times a coin with a rating of 1.
The standard ratings are as follows: 
The NGC has two professional numismatists grade every coin. These coin graders are not involved in the buying or selling process and have no knowledge of the submitter, so their grades are entirely impartial. The coin graders assess the coin for quality and assign it a number between 1 and 70 that aligns with the universally accepted numismatic grading scale. 
NGC may also assign additional designations to the coin: 
PCGS graders are trained to handle any type of coin, but they are assigned coins to grade based on their personal strengths, so each coin is assessed by the best person for the job. At least three graders evaluate each coin. If the first two graders agree, a third grader is used to verify their assessments. If the first two graders disagree on their evaluation, the third grader acts as a tie-breaker, and a fourth grader verifies the assessment. 
In addition to a standard rating from 1 to 70, PCGS may assign the following designations to their coins: 
Coin grading was inconsistent and subjective through the 19th century and into the first half of the 20th century. The manner of coin grading changed in 1949 when Dr. William Sheldon created the 70-point grading scale detailed in the previous section. He designed this scale for pennies made between 1793 and 1814, but it quickly caught on and became standard for other coins as well.
In 1977, Abe Kosoff's book, 'The Official ANA Grading Standards for United States Coins,' was published. Kosoff defined the numerical grades clearly for the first time, and he added descriptions to accompany each major rating, such as MS for 'Mint State.' This gave more detail to Sheldon's system and was adopted as a welcome addition to this standard.
The ANA Certification Service was established in 1972 and began offering grading services in 1979. PCGS started in 1986, and NGC followed in 1987. These two services quickly became the standard for most coin collectors and sellers.
Eventually, PCGS began to encapsulate the coins they graded in clear plastic holders, which collectors call 'slabs.' The grades of the coins that are kept safe within their protective packaging are guaranteed. This allows buyers and sellers to confidently execute remote transactions with a solid understanding of what kind of coin they're getting.
