Why did framers give congress the power to issue currency?

The initial idea was that a strong currency could be created at the national level, thereby creating a unique national monetary system.

The US dollar is the official currency of the United States of America. Usually the name used by the currency is usually associated with the legal circulation in that country. After the break of the gold standard in 1971, the currency became, de facto, a fiat currency.

both are true, the congress does have the power to create banks, even if this power is not specifically described in the constitution, since there is nothing restricting it and there is power given to the congress to make "all laws which shall be necessary and proper". maryland was not allowed to tax a branch of the national bank operating there, and the supreme court decided that no state could. both of these topics were discussed in a decision of the mcculloch v. maryland case in 1819.

yes they have. but is this a true false question? if it is, the answer is true.
