A Fist Full of Dollars

Decimalization

The concept of decimalization played a pivotal role in the adoption and naming of the dollar across various countries. Gary Arndt explains that the United States was an early adopter of decimalized currency, following the Russian ruble, which made the term "dollar" synonymous with decimalized currency systems 1. This association led many Commonwealth countries to adopt the name "dollar" when they transitioned to decimalized currencies, distinguishing them from the non-decimalized British pound.

The US dollar was the second currency after the Russian ruble to become decimalized. And in the 19th century, the word dollar became associated with a decimalized currency.

The British, on the other hand, did not decimalize their currency until 1971, which further solidified the dollar's identity as a modern, decimalized currency 1.

   

Coin Evolution

The evolution of coins and denominations associated with the dollar reflects a rich historical context. Gary Arndt notes that the American penny's name derives from "pennyweight," a term linked to sterling silver weight 2. The nickel, introduced in 1866, replaced the silver half-dime and is unique to the US and Canada. The term "dime" comes from the French word for "tithe," indicating a tenth, while the quarter's origin is tied to the Spanish "pieces of eight."

The American and Canadian five-cent coin is known as a nickel due to the metal it is composed of.

Interestingly, the US is one of the few countries still using a paper $1 note, despite attempts to circulate dollar coins, which failed due to their similarity in size to quarters 2.

   

Dollar Sign

The history and design of the dollar sign reveal intriguing origins and variations. Gary Arndt explains that the one-line variant of the dollar sign was originally used for the Spanish peso, with the large "S" representing Spain and a "P" as a superscript 2. Over time, the "P" merged with the "S," leaving a vertical line through the "S."

What we call the dollar sign is also the peso sign, which is used today in countries that use that currency.

The double-line variant, possibly a monogram of "U" and "S," has largely fallen out of use and is not part of the Unicode character set, highlighting the evolution and adaptation of currency symbols 2.
