In the 1500s, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English), named for Joachimstal, the valley where the silver was mined (St. Joachim's Valley, now Jáchymov; then part of the Holy Roman Empire, now part of the Czech Republic).[17] Joachimstaler was later shortened to the German Taler, a word that eventually found its way into Danish and Swedish as daler, Dutch as daalder, Ethiopian as talari, Italian as tallero, Flemish as daelder, and English as dollar.[17] Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal.



The symbol $, usually written before the numerical amount, is used for the U.S. dollar (as well as for many other currencies). The sign's ultimate origins are not certain, though it is possible that it comes from the Pillars of Hercules which flank the Spanish Coat of arms on the Spanish dollars that were minted in the New World mints in Mexico City, Potosí, Bolivia, and in Lima, Peru. These Pillars of Hercules on the silver Spanish dollar coins take the form of two vertical bars and a swinging cloth band in the shape of an "S".[18]

An equally accepted, and better documented, explanation is that this symbol for peso was the result of a late eighteenth-century evolution of the scribal abbreviation "ps." The p and the s eventually came to be written over each other giving rise to $.[19][20][21]

A fictional possibility suggested is that the dollar sign is the capital letters U and S typed one on top of the other. This theory, popularized by novelist Ayn Rand in Atlas Shrugged [22], does not consider the fact that the symbol was already in use before the formation of the United States[23], or that the dollar sign does not actually look like a capital letter U and S typed one on top of the other.
