Coin grading is the process of determining the grade or condition of a coin, one of the key factors in determining its collectible value. A coin's grade is generally determined by six criteria: strike, preservation, luster, color, attractiveness, and occasionally the country/state in which it was minted. Several grading systems have been developed. Certification services professionally grade coins for tiered fees.

The American Gold Eagle is an official gold bullion coin of the United States. Authorized under the Gold Bullion Coin Act of 1985, it was first released by the United States Mint in 1986. Because the term "eagle" also is the official United States designation for pre-1933 ten dollars gold coins, the weight of the bullion coin is typically used when describing American Gold Eagles to avoid confusion. This is particularly true with the 1/4-oz American Gold Eagle, which has a marked face value of ten dollars.
The American Platinum Eagle is the official platinum bullion coin of the United States. In 1995, Director of the United States Mint Philip N. Diehl, American Numismatic Association President David L. Ganz, and Platinum Guild International Executive Director Jacques Luben began the legislative process of creating the Platinum Eagle. After over two years of work, the 99.95% fine platinum coins were released by the United States Mint in 1⁄10, 1⁄4, 1⁄2 and 1 troy oz denominations. In late 2008, the fractional denominations were discontinued, leaving only the one ounce denomination. The Platinum Eagle is authorized by the United States Congress, and is backed by the United States Mint for weight, content, and purity.

The West Point Mint is a U.S. Mint production and depository facility erected in 1937 near the U.S. Military Academy in West Point, New York, United States. As of 2019 the mint holds 22% of the United States' gold reserves, or approximately 54,000,000 troy ounces (1,700,000 kg). The mint at West Point is second only to the gold reserves held in secure storage at Fort Knox. Originally, the West Point Mint was called the West Point Bullion Depository. At one point it had the highest concentration of silver of any U.S. mint facility, and for 12 years produced circulating Lincoln cents. It has since minted mostly commemorative coins and stored gold.
