Low prices, even if the items couldn't be reforged, still caused a rush among merchants.
This gave Roman significant financial flexibility.
Because he was truly experiencing a scarcity of metal coins, in order to upgrade the "Angel Envoy" panel, he nearly bankrupted himself. He would have had to issue IOUs for compensation or offset it with physical goods otherwise.
It wasn't just him experiencing scarcity.
The nobles were also very short on such metal resources.
Gold, silver, copper, iron.
These four metals held value because they could be directly exchanged for exceptional resources.
They could be magnificently transformed into—Fine Gold, Mithril, Mountain Copper, Magic Steel.
The value of precious metals would fluctuate only with resource mining and social development.
But if the metals themselves had strategic value, that too would affect their value.
Even Mountain Copper wouldn't be much cheaper than gold.
