This papercraft is really pointless, a request from my Singaporean friend David. Hey David now you can download this e-book (PDF) and get rich extremely fast, I can guarantee that! haha.
The United States dollar (sign: $; code: USD) is the unit of currency of the United States and is defined by the Coinage Act of 1792 to be between 371 and 416 grains (27.0 g) of silver (depending on purity). The U.S. dollar is normally abbreviated as the dollar sign, $, or as USD or US$ to distinguish it from other dollar-denominated currencies and from others that use the $ symbol. It is divided into 100 cents (200 half-cents prior to 1857).
