Step-by-step explanation:
The Coinage Act of 1792 established bimetallism as the monetary standard for the United States, allowing both gold and silver to be used as legal tender for payments of debts. The act also authorized the minting of several types of coins, including silver dollars, which were heavily used in commerce at the time. However, in 1873, Congress passed the Fourth Coinage Act, which dropped the silver dollar from the list of coins to be minted, effectively ending bimetallism in the United States. This act was also known as the "Crime of '73" by those who believed it was a deliberate attempt to favor the interests of gold producers over silver producers.
