Paper money is a custom blend of 25% cotton and 75% linen. It’s closer to cloth than paper. This blend, which can not legally be used by anyone outside the Bureau of Engraving and Printing, is much more durable than ordinary paper.
U.S. coins are mostly made of a mixture of copper and nickel. Some people think we don't need pennies any more. The penny, which most people believe to be made of copper, is actually copper-plated zinc. The nickel is made a 75% copper and 25% zinc blend. This same mixture of metals, called an "alloy," is used for the outer layer of quarters and dimes. But look at the edges of these coins. There is a reddish-colored layer inside. This is a core of pure copper.
The gold coin is not gold. It’s another pure copper core sandwiched between layers of manganese brass, made up of 77% copper, 12% zinc, 7% manganese and 4% nickel

Currency paper is composed of 25% linen and 75% cotton. Red and blue synthetic fibers of various lengths are distributed evenly throughout the paper. Prior to World War I the fibers were made of silk.
