Samuel Nelson, Ballard v. Thomas — Opinion of the Court
“ The iron was shipped from Liverpool, and, on an appraisal at the custom-house in Baltimore, the invoice price was adopted as the minimum market value upon which to assess the duties. The plaintiffs claimed that the iron ought to be appraised at the actual cash market value, or cash wholesale price, instead of the actual market value or wholesale price at a credit of four months, the usual time in the purchase of iron. But the collector insisted upon the invoice price as the minimum valuation. ”
