With a cigarette in one hand and a money- marking pen in the other, Kuhl began his quest to conquer the dollar by thumbing through thick binders of paper samples. Money-marking pens draw a black line on paper made with starch but not on stock that lacks starch, such as the ultrafine cotton-linen sheets manufactured by Crane & Co. of Dalton, Massachusetts, the sole provider of US dollar substrate. He contacted a dealer in Düsseldorf, hoping to buy some of Crane’s special blend of 75 percent cotton and 25 percent linen, but he was told that selling it was forbidden. Eventually Kuhl connected with a dealer in Prague who supplied him with starch-free paper that felt and weighed about the same as the Crane’s.

Kuhl’s intricate production process combined offset printing with silk-screening (see “How to Make $100″). The hardest features to forge with any level of sophistication are on the front of the note: the US Treasury seal, the large “100″ denomination in the bottom-right corner, and the united states of america at the top. Real US currency is printed on massive intaglio presses (intaglio is Italian for engrave). The force with which the presses strike the paper lying over the engraved steel plates creates indentations that fill with ink, giving the bills a delicate 3-D relief and a textured feel. Its absence is a telltale sign of a counterfeit. For Kuhl this was the most critical puzzle piece: how to create that texture convincingly without the benefit of actual engraving. “I had an idea,” he says, “and I was itching to try it.”
