This is a hefty subject to take on so I commend you for tackling it.

But you skipped the most important piece of history that set the entire Gold Standard - Grant’s Public Credit Act of 1869. After the Civil War, Grant repaid US bonds in gold to try to get the economy back on back. And then panic hit with Black Friday and the Gold Ring which forced up the price of gold. (Also 1869.)

It took years to recover from it.
