The correct response regarding the difficulty Andrew Jackson would have faced in implementing his preferred currency of gold and silver coin is:
The U.S. stock of gold and silver was too limited under Jackson's presidency to provide a sufficient money supply.
During Jackson's presidency, while he favored a hard currency backed by gold and silver, the total available stock of these metals was indeed limited, which would have posed a challenge in establishing a sufficient money supply based on his preferred system. This limitation could hinder economic growth and create deflationary pressures, as there would not be enough currency in circulation to support a growing economy.
