There, "dollars" is a reference to the Spanish milled dollar , a coin that had a monetary value of 8 Spanish units of currency, or reales. In the U. Congress passed a Coinage Act. Section 9 of that act authorized the production of various coins, including "DOLLARS OR UNITS—each to be of the value of a Spanish milled dollar as the same is now current, and to contain three hundred and seventy-one grains and four sixteenth parts of a grain of pure, or four hundred and sixteen grains of standard silver".

The term eagle was used in the Coinage Act of for the denomination of ten dollars, and subsequently was used in naming gold coins. Paper currency less than one dollar in denomination, known as "fractional currency", was also sometimes pejoratively referred to as "shinplasters". Today, USD notes are made from cotton fiber paper, unlike most common paper, which is made of wood fiber.

In the 16th century, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers , named for Joachimstal , the valley where the silver was mined. The German word for valley is thal , or nowadays usually Tal cognate with "dale" in English.
The coins minted at Joachimsthal soon lent their name to other coins of similar size and weight from other places. One such example, was a Dutch coin depicting a lion, hence its Dutch name leeuwendaler in English: The leeuwendaler was authorized to contain It was lighter than the large-denomination coins then in circulation, thus it was more advantageous for a Dutch merchant to pay a foreign debt in leeuwendalers and it became the coin of choice for foreign trade.
It was also separately popular throughout Eastern Europe, where it led to the current Romanian and Moldovan currency being called leu literally "lion".

The American dollar coin was initially based on the value and look of the Spanish dollar or piece of eight , used widely in Spanish America from the 16th to the 19th centuries. The first dollar coins issued by the United States Mint founded were similar in size and composition to the Spanish dollar, minted in Mexico and Peru. The coinage of various English colonies also circulated. The lion dollar was popular in the Dutch New Netherland Colony New York , but the lion dollar also circulated throughout the English colonies during the 17th century and early 18th century.
