Why is the dollar referred to as a 'buck'?

The term "buck" as a slang term for the dollar has an interesting origin. There are a few theories regarding its etymology, but one commonly accepted explanation is related to the historical use of buckskins as a form of currency in early America.

During the colonial era, before the United States had its own currency, various forms of exchange were used. One such medium of exchange was the buckskin, which referred to the hides of deer or bucks. These buckskins were valued and traded among early settlers, Native Americans, and fur traders.

Over time, the term "buck" became associated with the idea of a unit of value. As the United States established its own currency, the dollar, the slang term "buck" continued to be used to refer to the currency.

Another theory suggests that the term "buck" originated from poker games in the 19th century. In those games, a buckhorn-handled knife was often used to mark the position of the dealer. This marker was known as a "buck." Eventually, the term was extended to represent a dollar.

Regardless of the exact origin, "buck" has become a widely recognized slang term for the dollar, and it is still commonly used today.
