Working Stock is the portion of the U.S. Government gold reserve which the Mint uses as the raw material for minting congressionally authorized coins and consists of bars, blanks, unsold coins and condemned coins.
The gold reserve held by the Department of the Treasury is partially offset by a liability for gold certificates issued to the Federal Reserve Banks at the statutory rate, which the Treasury may redeem at any time.
