Coins use the “Sheldon Scale” of Grading:

  • The 70-point system indicates “70” as a perfect coin.  (There has never been a coin graded as a “70” prior to the 1940’s).
  • Mint State (MS) coins are the preferred coins, especially when purchasing Pre-33 gold.
  • MS65 is GEM quality and highly recommended.

There are 3 major grading service companies:

  1. Professional Coin Grading Service was formed in 1985. PCGS has always held a high standard in the coin industry.
  2. Numismatic Guarantee Corporation was formed in 1986.
  3. Certified Acceptance Corporation was founded In November 2007 by leading members of the numismatic community to establish stringent standards for quality within a grade. Fifteen years later in 2022, CAC formed a Grading Service, utilizing the same stringent standards, with an unparalleled level of expertise, to every submitted coin – CACG.

Recommendations regarding grading and certification:

  • Buying the highest-grade coins is KEY when building an Ultra Rare portfolio.
  • Some of these great rarities can be in AU condition (About Uncirculated). AU coins still have mint luster, but also have a little wear.
  • When building your portfolio, always invest in the best.
  • The higher the grade, the more rare the coin is and the greater appreciation you will yield.
  • When purchasing Rarity, always buy CAC certified coins.
  • PCAG, Inc. is an authorized CAC representative company.
