George Shiras, Jr.,
Missouri Trust Company v. Krumseig…
“ More frequently there is a collateral agreement whereby the borrower is to purchase an article of property and to pay therefor more than its intrinsic value. It has been frequently held that to constitute usury, where the contract is fair on its face, there must be an intention knowingly to contract for or to take usurious interest, but mere ignorance of the law will not protect a party from the penalties of usury. ”
