In order to shore up the problem of outflow of gold and silver to pay for silk and spices from the east, would it be plausible for an emperor to move away from a gold/silver standard currency? Would the users accept it? How difficult would it be to persuade people to see past the intrinsic "worth" of gold and silver and consider currency as a fiat instead? Would it be too easy to counterfeit? Would it stop the inflation problem or just worsen it as later less disciplined emperors mint currency whenever they felt need?
