>>24127962Minerally rich and relatively advanced /who/ most likely has a currency system backed by gold. Banknotes made of high-quality papers are used with coins minted primarily with copper(and maybe a bit of silver alloy for higher valued ones). There still isn't a name for /who/'s money, though I arse pulled the name Republican Beryl a while before in a brainstorming session.
