A buck, a single - the dollar bill is perhaps the most recognized legal tender around the world. But did you know that before the American Revolutionary War, coins made up the U.S.'s currency - and there was not a dollar in sight.
Despite the dollar bill not being introduced until 1862, coins were unpopular with Americans. One reason was the size compared to the value of the coin - the gold dollar (introduced in 1848) was a exceptionally small coin. The fact that a dollar coin was worth around a day's wage when it was in use and that is was so easy to lose made the coin so unpopular.
The gold dollar coin was made of 90% gold and was the smallest denomination of gold currency ever produced by the United States federal government. In the late 1840s, after America saw great gold rushed, Congress was interested in putting more gold to use in the form of currency.
In 1849, the Liberty Head coin - the first of three types of gold coins - was circulated.
In 1854, the size of the gold dollar coin was increased. Most of the third type of gold coins, which was produced in 1856-1889, were used to pay for interest on Government bonds and the cost of the Civil War.
It was only in 2011 that the Mint halted all production of dollar coins for circulation, meaning that they became collectors' pieces only.
