The authority to coin money is a federal power because money must be uniform across the entire country for commerce to work smoothly. The Constitution gives Congress the power to coin money and regulate its value, so minting coins and issuing currency belongs to the national government.

States and municipalities handle many local functions, but currency creation is reserved for the federal government, aligning with nationwide monetary policy and the single national currency.
