Joseph Story,
Bank of the United States v. Waggener…
“ Did they intend usury, and make use of any shift or device to cover a loan of money? Or did they, bona fide, intend a loan of bank notes, which to the lender were of the full value of their numerical amount, and were so treated bona fide by the borrower? Unless the court were prepared to say, (which we certainly are not) that all negotiations for the sale or exchange of bank notes, under any circumstances, must, to escape the imputation of usury, or the prohibition of the charter, be merely at their marketable value at the time, though worth more to both parties ”
