Old Book shows how Constitutional money system worked

[Rock Anthony]

Stunning Book! Just finished reading it and so much of it forms the base upon which the current crap was constructed.
The galactic elephant in the room is this: The Coinage act of 1792 fixed what a dollar is according to the Constitution. A "Dollar" is mentioned 2 times in the Constitution and Bill of Rights. (Article1 section 9, and the 7th amendment).

Every "act" of CONgress since then purporting to change the "dollar" is a fraud is it not? The only way the definition of "dollar" can be changed is via amendment to the constitution. Am I right or wrong?

See section 8 of Article One of the United States Constitutionwiki:

To coin money, regulate the value thereof, and of foreign coin, and fix the standard of weights and measures;

A 'dollar' is a unit of measure. It is definitely within the powers of Congress to change the definition of the dollar.

And while the Constitution grants to US Congress the power to define the dollar, the dollar is not defined within the US Consitution. The definition of the dollar is defined through acts of Congress. Therefore, no amendment to the Consitution is needed to meddle with the definition of the dollar.
