Roger B. Taney,
Andrews v. Pond — Opinion of the Court
“ And in order to enable the jury to decide whether usury was concealed under the name of exchange; evidence on both sides ought to have been admitted, which tended to show the usual rate of exchange between New York and Mobile, when this bill was negotiated. There is no rule of law fixing the rate which may be lawfully charged for exchange. It does not altogether depend upon the cost of transporting specie from one place to another; although the price of exchange is, no doubt, influenced by it. ”
