The American Silver Eagle coins in this category have been graded by the Professional Coin Grading Service (PCGS), the first and oldest third-party coin grading service. PCGS, along with the National Guaranty Corperation (NGC), are considered the top tier or “gold standard” in coin grading.
Every Silver Eagle submitted for grading is first certified as genuine, then carefully examined under 5x magnification by professional coin experts.
Both NGC and PCGS use a modified form of the Sheldon Scale of Coin Grading, a 70-point scale for grading coins developed by Dr. William Sheldon in 1949. In fact, the founders of PCGS helped the American Numismatic Association establish the standardized coin grading criteria in 1985.
American Silver Eagles are the official United States 1 oz silver bullion coin. They are among the best known 1 oz silver bullion coins on the market today. Sales of American Silver Eagles have risen sharply following the 2008 financial crisis. There have been more than 300 million American Silver Eagle bullion coins sold by the U.S. Mint since the program started in 1986, and this number doesn't even count proof or burnished versions!
The design on the coin’s obverse is based on the “Walking Liberty” design by Adolph A. Weinman, which was used on half dollar coins minted from 1916 to 1947. Silver Eagles are currently minted by the West Point Mint and the San Francisco Mint.
A high-scoring Silver Eagle professionally graded by a third-party service can be worth far more than an ungraded example, and ease resale later.
