Step-by-step explanation:
The period when more than 10,000 different banknotes circulated throughout the country was the 19th century. This event took place after the demise of the first national bank when Congress refused to recharter the Bank of the United States in 1811.
As the Second Bank of the United States was created to stabilize the system in 1816, the number of state banks, nearly all issuing their own paper money, began to increase. This proliferation of various banknotes without standard value contributed to significant economic issues, such as the Panic of 1819. The correct option for the question is a. 19th century.
The United States saw significant shifts in banking practice during this time.
