Who verifies the value of government money?

[OldDeckHand]

"Who verifies the gold or silver content of a coin?"

The USC (Art I, Sec 8) stipulates that Congress be vested in establishing weights & measures. Congress has written legislation that demands the Executive enforce those regulations.

"Who verifies the value of government money?"

The free market. As it should be.

Every transaction verifies the value of “government money”.

Now a bill or coin could be a counterfeit but that is a different issue.
