Moreover, the obligatory uses of legal-tender money are in fact very inconsiderable. A law requiring a past debt to be satisfied with money of a certain kind has for its essence only the payment of something of a definite value, or its equivalent; in practice, it does not even bring about the actual use of a legal money, since the monetary habits of the community will not necessarily require the debt to be paid in such money. Take the extreme case of a judgment by a court against a defendant for fulfilment of a contract; in such an example, of all others, it would be supposed that legal money would be exacted. But even here, the judgment would most probably be satisfied by the attorney's check, or at most by a certified check. If such media of exchange are of common usage in the community they will be resorted to in practice even for legal-tender payments. The necessity of paying that which would be mutually satisfactory to payer and payee also makes clear why the existence of a legal-tender money does not necessarily cause its actual use in payments. The business habits of the community are stronger than legislative powers. Business men will not as a rule take advantage of a legal-tender act to pay debts in a cheaper money, if they look forward to remaining in business. For, if, by taking advantage of legal devices they defraud the creditor, they cannot expect credit again from the same source; and since loans are a necessity of legitimate modern trade, such action would ruin their credit and cut them off from business activity in the future. Gold was not driven out of circulation by paper money during the years 1862-1879 in California, because the sentiment of the business public was against the use of our depreciated greenback currency; and a discrimination was made against merchants who resorted to the use of paper.
