A Beginner's Guide to Coin Grading: Understanding the Basics

Are you new to coin collecting and wondering how the value of your coins is determined? One key factor to consider is the coin's condition, and this is quantified through a process known as coin grading. In this guide, we'll explore the basics of coin grading, especially tailored for novice collectors.


The Grading Scale

Coins are graded on a scale of 1 to 70, with 1 being the lowest and 70 representing the most pristine condition. This scale, created by Dr. William Sheldon in 1949, plays a crucial role in determining the value of a coin. Grading companies evaluate coins and encase them in sealed plastic holders with the assigned grade, providing a standardized reference for collectors.

The Sheldon Scale: A Foundation for Coin Grading

The Sheldon Scale, a fundamental tool in coin grading, was developed by Dr. William Sheldon in 1949. This innovative grading system aimed to provide a standardized method for determining accurate pricing based on the overall condition or state of preservation of large cents. Dr. Sheldon's scale revolutionized the numismatic world, providing collectors with a common language to assess and compare the condition of coins.

The Birth of the Sheldon Scale

Dr. William Sheldon, an American numismatist and economist, recognized the need for a systematic approach to evaluating the condition of coins. Prior to the Sheldon Scale, there was a lack of consistency in describing a coin's state of preservation, leading to ambiguity in pricing and trading. Dr. Sheldon sought to address this issue by creating a numerical scale that would reflect the quality of a coin's preservation.

The Numeric Grading Scale The Sheldon Scale ranges from 1 to 70, with each number corresponding to a specific grade. The lowest end of the spectrum, Grade 1, represents the poorest condition, while Grade 70 represents the most pristine example possible. This scale provides a comprehensive and standardized way to communicate the condition of a coin, aiding collectors, dealers, and enthusiasts in making informed decisions.

Pricing and Condition Correlation

The key principle behind the Sheldon Scale is the correlation between a coin's condition and its market value. According to this principle, the better the condition of a coin, the higher its price. For example, a coin graded as Good 4 would be priced lower than a coin graded as Fine 12. Dr. Sheldon's scale provided a method to objectively assess the value of coins based on their state of preservation.

Legacy and Impact

The Sheldon Scale's legacy endures as the backbone of coin grading. Its influence extends beyond large cents to encompass the grading of coins of various denominations and types. The scale has been refined over the years, and its principles continue to guide numismatists in evaluating and understanding the condition of coins.

Understanding the Scale
  • Poor 1, Fair 2, and Almost Good 3 (PO-1, FA-2, AG-3): Coins with lower grades exhibit heavy wear, with discernible type and date but minimal detail. Interestingly, Poor 1 coins can be valuable for collectors interested in the history associated with well-worn coins.
  • Good 4, 6, and Very Good 8, 10 (G-4, G-6, VG-8, VG-10): The design becomes more visible, with varying degrees of detail, but all show signs of heavy circulation.
  • Fine 12, 15, and Very Fine 20, 25, 30, 35 (F-12, F-15, VF-20, VF-25, VF-30, VF-35): Lettering and digits become clear, with circulation wear visible on high points.
  • Extremely Fine 40 and 45 (EF-40, EF-45): Minimal wear noticeable under close inspection, with traces of original mint luster.
  • Almost Uncirculated 50, 53, 55, and 58 (AU-50, AU-53, AU-55, AU-58):Attractive coins with minimal wear, often mistaken for uncirculated specimens.
  • Mint State 60-70 (MS-60 to MS-70): Coins with no evidence of circulation wear, and the differences within Mint State grades are based on factors like strike quality, luster, and general eye appeal.

  • Details Grades Coins with undesirable flaws, such as cleaning, scratching, mishandling, or environmental damage, receive a "details" grade, lowering their value. Verbal descriptors are provided for the overall condition.
  • Major Coin Certification Companies: NGC and PCGS

    In the world of coin collecting, two prominent organizations play a pivotal role in the certification and grading process: Numismatic Guaranty Corporation (NGC) and Professional Coin Grading Service (PCGS). These certification companies are trusted by collectors and dealers alike for their expertise in evaluating and grading coins.

    Numismatic Guaranty Corporation (NGC) NGC, founded in 1987, has become a globally recognized authority in coin grading and certification. Known for its stringent grading standards and innovative technology, NGC employs a team of expert graders who meticulously assess coins for their condition and authenticity. Coins certified by NGC are encapsulated in a protective holder, ensuring their preservation and providing a clear display of the assigned grade.

    NGC offers additional services, such as designations for special coins and pedigrees that trace a coin's ownership history. Collectors often appreciate the consistency and reliability of NGC grades, making it a preferred choice in the numismatic community.

    PCGS - Professional Coin Grading Service

    Professional Coin Grading Service (PCGS) Founded in 1986, PCGS is another industry leader in coin grading and authentication. Renowned for its accuracy and reliability, PCGS employs a team of highly experienced graders who utilize advanced technology to evaluate coins. PCGS-certified coins are encapsulated in a tamper-evident holder, providing protection and ensuring the integrity of the grade assigned.

    PCGS introduced the concept of the "First Strike" designation, indicating that a coin was struck within the first 30 days of minting. This distinction adds another layer of information for collectors. PCGS also offers special labels and designations for coins with historical significance or unique characteristics.

    An up and coming Grading Service: Certified Acceptance Corp

    Founded in 2007, the Certified Acceptance Corporation (CAC) set out to establish stringent standards for coin grading, addressing the market's lack of confidence in consistent quality. In 2022, CAC expanded its influence with CAC Grading, maintaining the same rigorous standards within a grading service. With a team of world-class graders, CAC Grading ensures an unparalleled level of expertise. The impact is evident as collectors entrust their sets for certification, making CAC synonymous with premium quality in the rare coin market. The recognizable CAC sticker and CAC Grading instill confidence in the value of certified coins, commanding a premium due to their commitment to accuracy and consistency.

    Choosing Between NGC, PCGS and CAC

    Both NGC and PCGS are respected in the numismatic community, and the choice between them often comes down to personal preference. While CAC is making headway with collectors, it is also combined with NGC and PCGS pieces as an extra level of grading validation. Some collectors may favor NGC for its grading consistency, while others may appreciate PCGS for its innovative designations and additional services. Discriminating collectors will want the additional verification of grade on higher-end pieces as a matter of security.

    Ultimately, these companies contribute to the credibility and standardization of coin grading, providing collectors with confidence in the authenticity and condition of their coins.
