Learn Grading: American Silver Eagles

NGC - NGC grades most coins on a scale of 1 to 70. There are subtle differences near the top of the scale, which covers nearly the entire population of modern bullion coins like the Silver Eagle.

NGC uses a numeric grade to succinctly describe a problem-free coin's condition. NGC's Coin Grading Scale is based on the internationally accepted Sheldon Scale, which runs from 1 to 70.

The numeric grade is typically preceded by an abbreviation that indicates the way the coin was struck and, for circulation issues, its approximate condition. The numeric grade is sometimes followed by a designation called a "strike character" that sheds further light on the coin's condition. Examples of NGC grades include NGC MS 70 and NGC PF 70 Ultra Cameo.

The American Silver Eagle is the official silver bullion coin of the United States, and NGC has graded more Silver Eagles than any other coin — over 10 million of them! The US Mint released the bullion 2020 Mint State Silver Eagles and the 2020-W Proof Silver Eagles in January, and is expected to release other Silver Eagles including other Mint State and Proof versions — throughout the year.

Here, we examine how NGC determines what numeric grade to assign a Silver Eagle. A quick look at the NGC Census reveals that 99% of Silver Eagles are graded 67 to 70, so we will focus on those grades.

MS/PF 70

For a Silver Eagle to receive the highest grade on the NGC Grading Scale, it must have no post-production imperfections visible at 5x magnification. This is the most sought-after grade, as collectors prefer the best example possible.

Luster: Must be outstanding.
Contact Marks: No post-production contact marks are permissible.
Strike: Must be complete and sharp.
