    In 1784, Thomas Jefferson proposed a decimal currency system for the United States based on the Spanish dollar, with coins for 10 dollars, 1 dollar, 1⁄10 dollar, and  1⁄100 dollar. One argument he advanced in favor of this system was that the 1⁄100-dollar coin would be similar in value to existing copper coins. The initial currency of the United States was minted in 1792 with the dollar being equal to 100 cents. Working with decimals is essential when calculating or analyzing most currency data, whether it be from historical or modern times!
