What the heck happened to that country? The currency is so worthless. Being so worthless, it must be a fiat currency to boot, despite the civilization being relatively underdeveloped from our pov. Anyone in possession of gold in that country would be wise to not sell even one bit of it. Unless gold in that world is as common as iron in ours. In that case they should try to accumulate anything that would retain its value when the currency eventually plummets further.
