This is why my games always run on the silver standard. Each unit of currency is 100 times the value of the previous unit Instead of 10, and the listed prices that would have been gold are now in silver.

This makes it a lot less weird when dropping coin on watered down ale, stale bread, and a cot. And it also makes finding gold coins for the first time a lot more exciting. And when your characters start getting wealthy enough to actually carry gold and buy big ticket items with it, it actually feels like you’re getting rich.

And then there’s platinum. A single platinum coin becomes an event, the kind of thing that causes the greedy to become reckless and the experienced to become paranoid. It’s the perfect schmuck bait, a massive fortune in a single coin, all you have to do is pick it up. [Cue evil laugh]

Love it. These ridiculus “gold” prices in games and mangas etc have always been a pet peeve of mine
Well, they do take place in a fictional universe, where we can assume scarcity is different.
Still metallurgy is not cheap in terms of energy when you only have wood to burn!
Funnily, with gold you don’t even need heat for things like forming coins.
If i recall correctly, you can hammer the coin when it’s cold to put the decorations on it, but you still need to melt the metal at some point to get it at the right thickness and give it the circular shape. I may be wrong tho
