Final answer:
The U.S. faced currency issues during the Revolutionary War with the creation of Continental currency, which rapidly declined in value due to factors like excessive printing and counterfeiting by the British.
Step-by-step explanation:
The American colonies faced currency issues during their rebellion against the British, as they primarily used British paper money and foreign coins. After forming a new nation, the Americans created their own currency called Continental currency.
However, due to factors such as excessive printing, counterfeiting, and economic warfare by the British, the value of Continental dollars rapidly declined. This caused inflation and depreciation of the currency, leading to the expression 'not worth a Continental.'
