Which department is responsible for coining and printing money?

The Treasury Department is responsible for coining and printing money in the United States. This role includes overseeing the production of currency and coinage as well as implementing monetary policy through the management of the federal government's finances. The Bureau of Engraving and Printing, which operates under the Treasury, is specifically tasked with producing paper currency, while the U.S. Mint handles coin production.

This responsibility is rooted in the Treasury's broader mandate to maintain economic stability and manage the country's financial resources. The other entities listed do not hold this specific responsibility; for instance, the Federal Reserve manages monetary policy, but it does not directly print money.
