United States Mint
Also: U.S. Mint, US Mint
The United States Mint is the official coinage authority of the United States and has been issuing legal tender coins as well as bullion coins in gold, silver, and platinum since 1792.
The United States Mint (U.S. Mint) is the official coinage authority of the USA and was established by the Coinage Act of 1792. It operates under the U.S. Department of the Treasury and has a statutory mandate to produce circulation coins for everyday transactions, collector coins, and bullion coins for investors. For precious metal buyers worldwide, the U.S. Mint is best known as the issuer of the world's most widely traded bullion coins — its products are regarded as a benchmark for quality and counterfeit resistance.
Locations and Mint Marks
The U.S. Mint currently operates four active minting facilities:
| Location | Mint Mark | Focus |
|---|---|---|
| Philadelphia | P (or no mark) | Circulation coins, bullion |
| Denver | D | Circulation coins |
| San Francisco | S | Proof coins, collector items |
| West Point (New York) | W | Bullion coins, proof gold/silver |
The mint mark on a coin indicates the place of production and is an important authenticity feature.
Key Bullion Coins
American Eagle (since 1986): The best-known U.S. bullion coin has been struck in gold and silver since 1986; platinum Eagles followed in 1997. The gold Eagle is composed of a 22-karat alloy (916.7 ‰) with copper and silver additions for increased hardness — similar to the Krugerrand. The silver Eagle contains one troy ounce of silver at 999 ‰ fineness and is the world's best-selling silver bullion product.
American Buffalo (since 2006): In response to demand from investors who prefer pure gold, the U.S. Mint introduced the Buffalo at 999.9 ‰ fineness (24 karat). It is regarded as the counterpart to the Vienna Philharmonic and Maple Leaf.
The current gold price and silver price — and thus the intrinsic value of all bullion coins — are shown in real time on the respective price pages.
Quality Assurance and Authenticity Testing
Every U.S. Mint bullion coin carries precise weight, diameter, and thickness specifications. The Silver Eagle, for example, weighs exactly 31.103 g with a diameter of 40.6 mm. Deviations are a strong indicator of counterfeits. The coin weight checker allows quick comparison of nominal and actual values; the coin authenticity checker guides through further verification steps (magnet test, ping test, density).
Collector Coins and Proof Editions
In addition to bullion coins, the U.S. Mint produces high-quality proof versions (polished plate) with mirror-bright fields, as well as numismatic collector pieces. Proof editions often command a significant premium over the pure metal value. When making investment decisions between bullion and collector coins, the premium effect should be taken into account (this is not investment advice).
In Brief
The U.S. Mint stands for government-guaranteed quality and, with the American Eagle and American Buffalo, is the first choice for precious metal investors worldwide when it comes to recognised, liquid standard products.
