> Article I, Section 8, Clause 5 is known as the coinage clause. It gives Congress the exclusive power to coin money. The Supreme Court has also interpreted clause 5 as giving Congress the sole authority to regulate every aspect of United States currency.
That supreme court interpretation is from 1820 so it's both "settled law" and "an outdated ruling", depending on who you ask.
