Actually it's more a drawer in a file cabinet.

The agency, which is part of the Treasury Department, opened offices in Parkersburg in the 1950s as part of a plan to locate important government functions away from Washington, D.C., in case of an attack during the Cold War.
One bond is worth a little more than $15.1 billion, and another is valued at just under $10.7 billion. In all, the agency has about $2.5 trillion in bonds, all backed by the full faith and credit of the U.S. government. But don't bother trying to steal them; they're nonnegotiable, which means they are worthless on the open market.

All securities held by the trust funds are "special issues" of the United States Treasury. Such securities are available only to the trust funds.
In the past, the trust funds have held marketable Treasury securities, which are available to the general public. Unlike marketable securities, special issues can be redeemed at any time at face value. Marketable securities are subject to the forces of the open market and may suffer a loss, or enjoy a gain, if sold before maturity. Investment in special issues gives the trust funds the same flexibility as holding cash.
