The US Mint Facilities

There are six US mint facilities total, located in the following cities: Washington DC, Philadelphia, West Point, Fort Knox, Denver, and San Francisco. Because each of these US mint facilities perform a specific function, you may find some coins only come from certain locations.

• The Washington DC US Mint facility handles everything from the policies of the US Mint to the marketing and research and development.
• The Philadelphia US Mint facility handles the sculpting engraving process for US coins as well as the production of general circulation coins.
• The Denver US Mint facility handles Congress backed commemorative coins as well as the production of general circulation coins. This facility also stores silver and gold bullion.
• The San Francisco US Mint facility produces silver proof sets as well as Congress backed commemorative coins.
• The West Point US Mint facility produces all the uncirculated and proof silver bullion coins and American Eagle gold bullion and platinum bullion coins.
• The Fort Knox US Mint facility stores US gold bullion.

Survival Of The Coin Proof Set

Just how many coin proof set and uncirculated set packages remain intact is unknown, but according to Coin World Magazine, the number may be smaller than you might think. Annually, there are an unaccounted number of coin proof set packages opened up due to demand by coin collectors for individual coins within the sets. However, one thing is certain, the demand for individual coins within an intact set can drive up the price of the remaining intact versions.

One coin company in Richmond, VA estimates breaking up a total of 150,000 to 160,000 coin proof sets and uncirculated Mint sets every year. The entire count comes to about 3 million sets broken up over the last two decades.
