Portrait of Salmon P. Chase Salmon P. Chase Bronson v. Rodes — Opinion of the Court

A debt is the amount due in 'dollars' merely; the treasury note meets the debt because it is a dollar, not because it is the equal of a coin dollar; because it is one of the class that the contract calls for, and thus comes up to the contract, not because it is the equal of the best of its class. On a debt of one hundred gold dollars, and one hundred lawful dollars, the same amount is not now due; the same number of dollars is due, but not of the same kind. Just as a dozen large eggs and a dozen small ones are equally good to meet an agreement to deliver eggs simply.

Portrait of Salmon P. Chase Salmon P. Chase Bronson v. Rodes — Opinion of the Court

It is well understood that in the case of a contract for the future delivery of a commodity of a stipulated quantity and quality, each party takes the risk of a rise or fall in its market value. So, in the case of a contract for the payment of a specified sum, in money, at a future day, each party takes a risk; the debtor, of an appreciation of the currency, the creditor, of its depreciation. It is immaterial whether the change in the value of the currency is caused by the operation of uncontrollable monetary laws, or by the direct exercise of the sovereign power of the government.

Payment of money is delivery by the debtor to the creditor of the amount due. A contract to pay a certain number of dollars in gold or silver coins is, therefore, in legal import, nothing else than an agreement to deliver a certain weight of standard gold, to be ascertained by a count of coins, each of which is certified to contain a definite proportion of that weight. It is not distinguishable, as we think, in principle, from a contract to deliver an equal weight of bullion of equal fineness.
