Depository institution coin deposits are weighed by electronic scales that are located at Federal Reserve Offices and also at armored carrier facilities throughout the United States. Many cash offices throughout the Federal Reserve System have entered into legal agreements with local armored carrier transportation companies to serve as off-site coin terminal facilities to process institution's deposits and maintain inventories of verified coin.
Unlike currency, there is no need to sort the coins for fitness since coins are damaged very rarely. The average life of a coin is estimated to be 30 years. Generally, all coin accepted by the Federal Reserve System is weighed (at a Reserve Bank Office or by armored carriers) and redistributed to depository institutions when they place orders. The processing of entries for coin deposits and orders is identical to the process for currency - an institution's Federal Reserve account is credited for the amount of the coin deposit and/or debited for the amount of the coin order.
Since most Americans tend to accumulate coin for collection purposes, the Mint continues to produce between 3 and 30 billion coins per year to meet public demand (see Frequently Asked Questions). The U.S. Mint (Off-site Link) operates four minting facilities; however, only two - Denver, Colorado and Philadelphia, Pennsylvania - create the coins that are distributed by the Federal Reserve System. The two remaining minting facilities include the San Francisco Mint in California and the West Point Mint in New York. Both facilities manufacture various gold, silver and platinum numismatic proof, uncirculated and bullion coins and annual proof clad and proof silver coin sets of the circulating coins.
