The person who, by making a deposit of bullion, obtains both a bank credit and a receipt, pays his bills of exchange as they become due, with his bank credit; and either sells or keeps his receipt, according as he judges that the price of bullion is likely to rise or to fall. The receipt and the bank credit seldom keep long together, and there is no occasion that they should. The person who has a receipt, and who wants to take out bullion, finds always plenty of bank credits, or bank money, to buy at the ordinary price, and the person who has bank money, and wants to take out bullion, finds receipts always in equal abundance.
The owners of bank credits, and the holders of receipts, constitute two different sorts of creditors against the bank. The holder of a receipt cannot draw out the bullion for which it is granted, without re-assigning to the bank a sum of bank money equal to the price at which the bullion had been received. If he has no bank money of his own, he must purchase it of those who have it. The owner of bank money cannot draw out bullion, without producing to the bank receipts for the quantity which he wants. If he has none of his own, he must buy them of those who have them. The holder of a receipt, when he purchases bank money, purchases the power of taking out a quantity of bullion, of which the mint price is five per cent. above the bank price. The agio of five per cent. therefore, which he commonly pays for it, is paid, not for an imaginary, but for a real value. The owner of bank money, when he purchases a receipt, purchases the power of taking out a quantity of bullion, of which the market price is commonly from two to three per cent. above the mint price. The price which he pays for it, therefore, is paid likewise for a real value. The price of the receipt, and the price of the bank money, compound or make up between them the full value or price of the bullion.
