You can get an exact valuation of your coins with coin grading in Denver today, but it wasn’t always that way.

The History of Coin Grading

The grade of a coin, in numismatics, is a code that describes the physical condition of the coin. When coin collecting was still young, grading was far simpler. Early grading systems had three levels:

  • Good

The design on these coins was still visible, but they were worn by mass circulation.

  • Fine

The details on these coins withstood the test of time better than “good” coins and still had some mint luster.

  • Uncirculated

These coins were new condition with clearly defined details and a fresh off the mint appearance.

Three designations were enough to get by in those days when coin trading was among an elite few. As it became more popular, it was clear that a better grading system was needed. Discerning collectors noticed that some Fine coins were better than other Fine coins and that not all Uncirculated coins had the same luster and detail.

They added Very Good, Very Fine, Extra Fine, Almost Uncirculated and Gem Uncirculated to the system for more accurate evaluation standards. It didn’t take long for these to become outdated.

Today’s Grading System

By 1948, grading became much more comprehensive and efficient. Dr. William Sheldon standardized a system which has undergone very little change in the time since. The Sheldon Scale adopted the Good, Fine, Uncirculated designations and added a numerical scale from 1–70. “1” represented a coin worn almost into oblivion, and “70”, perfection.

Sheldon intended his system to apply to his favorite large coins, but others began using it and it adapted to become a worldwide standard.

  • MS-60 to MS-70–Uncirculated or Mint State.
  • AU-58–Very Choice About Uncirculated.
  • AU-55–Choice About Uncirculated.
  • AU-50About Uncirculated.
  • EF-45–Choice Extremely Fine.  In discussion, most numismatists call this grade “XF.”
  • EF-40Extremely Fine.
  • VF-30–Choice Very Fine.
  • VF-20Very Fine.
  • F-12Fine.
  • VG-8Very Good.
  • G-4Good.
  • AG-3About Good.
  • **There is also a separate descriptive prefix, “PR”, reserved for Proof coinage.  Numeric descriptors for the these coins remain the same.

Each number in the Mint State scale (uncirculated coins only) has its own specific definition. This list comes from the Fifth Edition of the Official ANA Grading Standard for United States Coins published by the American Numismatic Association:

  • MS-70–The perfect coin.  Has very attractive sharp strike and original luster of the highest quality for the date and mint.  No contact marks are visible under magnification.  There are absolutely no hairlines, scuff marks or defects.  Attractive and outstanding eye appeal.  Copper coins must be bright with full original color and luster.

Standard Setting for Coin Grading

Though the Sheldon Scale was leaps and bounds better than the earliest system, there was still room for error and disagreement. The uneducated eye missed seeing what the educated eye did and traders waged pricing wars on the basis of opinion. Without proper training and experience it was difficult to distinguish the difference between MS64 and MS65, which might mean hundreds or thousands of dollars.

A professional works with the precision of years of practice and training. When one tiny flaw changes the value of a coin by thousands of dollars, a professional assessment is a necessary element of coin trading.

If coin trading was limited only to rare coin dealers, there would be less need for standardizing the grading system. A wide array of people collect and trade coins with little training. It’s a popular addition to an investment portfolio today.

Though these collectors don’t know much about the grading system, they realize the value professional graders offer in helping them avoid missing out on the superior value of one coin over another. An MS64 has far higher value than an MS65 even though an investor can’t see a difference between them.

Sadly, untrained collectors can be victimized by dealers who pass off an inferior MS64 coin as an MS65. In the absence of a professionally certified standard, and it happens far too often. That’s why the industry finally turned to recognized grading services that untrained collectors can trust.

Professional graders receive training through seminars with The American Numismatic Association from beginner to advanced levels.

Grading Services

By the 1980s two professional grading services became recognized as the standard setters in the industry:

  • Professional Coin Grading Service (PCGS)
  • Numismatic Guaranty Corporation (NGC)

Each of these services carefully examine rare coins, identify their serial numbers, and determine their grades. They also tag the coin with this info and encapsulate it. Encapsulation protects the coin and actually makes it more valuable because it guarantees the coin has undergone grading by one of the accepted professionals in the industry.

All coin grading in Denver and other locations involves sonic sealing of the capsule and tamper-evident precautions. Encapsulated coins, called “holdered” or “slabbed” coins, constitute the majority of valuable rare coins traded on the market today.

Holdered coins have a guarantee by the grading services, the grade and value of the coin and result in honest trading and fair market values in exchanges. Certified coins eliminate your risk and possible misrepresentation from dealers.

Make the most of your rare coin exchanges. Secure the investment in your collection with professional coin grading in Denver.
