Essentially nothing is known about Boles, save that his name appears stamped on three ingots, two of which are dated in December, 1883. We do know that N. A. Boles was located in Prescott, Arizona. Of the three known bars, all use the odd expedient of punching a 1 over an 8 to make something resembling a $. They place the fineness of the bar on the left side of the face but neither indicates the metallic content, presumably leaving it up to the owner’s common sense. None of them indicates the bar’s value in any other way than a simple dollar value.
