The _interest_, therefore, of the credits given by the bank, may be demandable from the debtors in coin; and the transfers of interest made by the bank, to those who bring in notes for payment, may also be demandable in coin from the bank. These payments will bear a small proportion to the paper in circulation, as interest must be very low; and coming at fixed terms of payment, provision will easily be made for them. This regulation will support the coin of the country, and as the _interest_ of all the paper becomes demandable in coin, the intrinsic value of the _interest_ will effectually support the value of the _capital_. When paper issued for domestic circulation returns to a bank, were it not for the profits on their trade, I see no reason why a bank should pay in any other species of property than what it received; and if, by the interest they receive for their notes, they are abundantly indemnified for all the difference between paying in coin and in transfer, I think the public would be a gainer to dispense with that obligation in lieu of an abatement of interest; which would be an advantage to commerce, not to be counterbalanced by the other. Farther, the business of providing coin is totally different from that of supporting domestic circulation: it is founded on different principles: it requires men of a particular genius to conduct it: the difficulties to be met with are not constant; and therefore cannot form a regular branch of bank administration. 2_do_, The method of providing coin for domestic circulation is the business of mints, not of banks. I have, in the third book, treated very fully of the doctrine of coin, and of mints. I have shewn the difference between money, which _is the scale for reckoning value_, and coin, which _is certain denominations of money, realized in a proportional weight of the precious metals_. I have shewn how necessary a thing it was to impose the price of coinage upon the metals manufactured into coin: and I have said, that it was inconsistent with all principles, to allege that the metals, when coined, should thereby acquire no additional value. The expence, therefore, of providing the metals should be thrown upon those who want coin; and the mint should be obliged to convert gold and silver into coin, upon the demander’s paying the coinage. This coin loaded with the price of coinage, never will be sent abroad to pay a foreign balance; never will be locked up in banks, which will have little occasion for it. It will, therefore, remain in circulation, and serve those purposes for which the inhabitants think fit to employ it.
