Gold certificate. A certificate issued against a corresponding amount of gold (coin or bars) held
in the Treasury.  Gold certificates are issued in denominations of $20, 50, $100, $500, $1,000.
$5.000, $10,000. The issue of them is unlimited, except that it is suspended when the gold reserve
in the Treasury falls below $100,000,000. Gold certificates are exchangeable at the Treasury for
gold coin or any other money.  Gold certificates are not legal tender, but are receivable for
customs, taxes and all public dues and when so received may be reissued; they are *also
available for the reserves of national banks. They were issued payable to bearer only until 1888,
when a series payable to order was also provided by the Treasury Department, but in
denominations of $5,000 and $10,000 only. Gold certificates are, in effect, merely warehouse
receipts.
