Congress has the power to coin money.
The branch of government that has the authority to coin money in the United States is the legislative branch, specifically Congress. This power is granted to Congress by the U.S. Constitution in Article I, Section 8, which outlines the enumerated powers of Congress. The executive branch, headed by the President, does not have the authority to coin money. The judicial branch, headed by the Supreme Court, also does not have this power.
