The word buck in the sense “dollar” was originally short for buckskin, in other words, the skin of a male deer. In colonial America, especially in the southeastern colonies, American Indians hunted deer and prepared their hides to trade for European goods. “Bucks,” or buckskins, became a means of calculating the value of goods, and the word was transferred to the dollar when the deerskin trade came to an end.
