A new form of grading based on a 10-point scale was announced by Numismatic Guaranty Company (NGC) on November 16. The new system, named NGCX, is the first of its kind for coins.

The 10-point rating scale has long been the standard for most collectibles, including comic books, sports cards, trading cards and more. For coins, NGC calls the new scale “intuitive” and “accessible.”

For centuries, coins have been collected – for fun, for study, as an investment, and as a benchmark for success. In the late 1940s, a numerical scale of 1 to 70 was introduced by Dr. William Sheldon to describe the relative values ​​of US 1-cent coins. In theory, a coin rated 1 would be worth $1 and a coin rated 70 would be worth $70. The values ​​soon became useless, but the rating scale remained. NGC adopted the Sheldon grading scale when it was created in 1987. It remains the industry standard to this day.

Meanwhile, the Collectible Instinct has expanded to include comic books, sports cards, trading cards, video games and more – the list continues to grow as new categories emerge. , collectors seeking to protect and preserve the things they love. NGC says these collectibles are almost always rated on 10-point grading scales, which new collectors quickly recognize and easily understand.

“Each 10-point rating scale is precise and nuanced based on the type of collection,” he said in a press release.

The 70-point grading scale for coins isn’t going anywhere. Instead, NGC says it recognized an opportunity to attract new collectors to the hobby by using the power of X – NGCX – a 10-point grading scale for coins.

On the NGCX scale, 10 is the highest rating, equivalent to 70 on the traditional scale. The following grades cascade from 10. For example, a coin rated NGCX Mint State or Proof 10 has no imperfections at 5x magnification, such as a coin rated NGC Mint State or Proof 70. Similarly, an NGCX Mint State or Proof 9.9 is the same as an NGC Mint State or Proof 69 graded coin – each being a fully minted coin with nearly imperceptible imperfections.

Although there is no difference in quality between a score on the 10-point scale and a score on the 70-point scale, NGC says, “the difference for the hobby is exponential.”

Modern NGCX-certified coins, minted from 1982 to present, will be available at select retailers beginning in January 2023. For a list of eligible retailers, click here.

NGCX is not available for regular NGC submissions, which will continue to be scored on the 70-point scale.
