well mining and minting is also a solution but unfortunately if we go by the rules of feudal system then the rights to mine and mint coins belongs to the kings unless the king is weak or royal power is weak and secretly minting is dangerous since well getting caught is easy spicily coins since well its forbidden and are heavy and using them is even more risky and since nobles can’t own mines this makes it impossible.
and since the currency system is probably gold is stronger than silver and silver is stronger than copper since the rarer the metal the more valuable it is but that should depend on the world supply not just the kingdom which is why the value of gold in eastern roman empire was the same in western Europe even though eastern roman empire had more gold due to them having better mining techniques
