The paper of each colony being received in the payment of the provincial taxes, for the full value for which it had been issued, it necessarily derived from this use some additional value, over and above what it would have had, from the real or supposed distance of the term of its final discharge and redemption. This additional value was greater or less, according as the quantity of paper issued was more or less above what could be employed in the payment of the taxes of the particular colony which issued it. It was in all the colonies very much above what could be employed in this manner.
A prince, who should enact that a certain proportion of his taxes should be paid in a paper money of a certain kind, might thereby give a certain value to this paper money, even though the term of its final discharge and redemption should depend altogether upon the will of the prince. If the bank which issued this paper was careful to keep the quantity of it always somewhat below what could easily be employed in this manner, the demand for it might be such as to make it even bear a premium, or sell for somewhat more in the market than the quantity of gold or silver currency for which it was issued. Some people account in this manner for what is called the agio of the bank of Amsterdam, or for the superiority of bank money over current money, though this bank money, as they pretend, cannot be taken out of the bank at the will of the owner. The greater part of foreign bills of exchange must be paid in bank money, that is, by a transfer in the books of the bank; and the directors of the bank, they allege, are careful to keep the whole quantity of bank money always below what this use occasions a demand for. It is upon this account, they say, the bank money sells for a premium, or bears an agio of four or five per cent. above the same nominal sum of the gold and silver currency of the country. This account of the bank of Amsterdam, however, it will appear hereafter, is in a great measure chimerical.
