Final answer:
The unity of the U.S. currency was not lost with the Civil War, specifically referencing the Confederate currency during that time. The statement is False.
Step-by-step explanation:
The statement is False.
The unity of the U.S. currency was not lost with the Civil War. It is important to note that the context of this question is referring to the Confederate currency during the Civil War. The Confederate treasury notes lost value almost immediately after being issued, and by the end of the war, $1 in Confederate currency equaled about $0.02 in Union currency. This depreciation in value was due to multiple factors such as inflation, lack of faith in the Confederate government, and the printing of more money. However, it is important to differentiate between Confederate currency and the U.S. currency as a whole.
