Democratic (constitutionalist) President Jackson signs the Coinage Act of 1834, reducing the value of the gold Dollar, from 19.38 Dollars to 20.67 Dollars, per ounce of gold.  The value of the silver Dollar remains unchanged at 1.29 Dollars per ounce of silver.  Thus changing the fixed gold/silver ratio from 15:1 to 16:1.

       NOTE: This act was inflationary in that it attempted to defy Gresham’s Law (Bad money drives out good money).  Rather than try to implement a “fixed standard” between the two lawful monies, a more practical solution is offered by Murray Rothbard: allow for a “parallel standard” between gold and silver, where buyers and seller can trade in the medium of exchange that they agree upon, either gold or silver, regardless of their free market exchange rates.
