You guys want a game that can evolve itself?... have the player base able to create currency. Yes. Coins from ore. Of course, the more printed/made in the game, the less value they are. I don't know how you would stop everyone from making an alternate toon and just creating their own gold. You could limit the amount of 'coin smiths' in game. Not sure if that is truely viable.

Or you could go with the multiple currency. You have 10 races in the game. You might have 6 or 7 currencies. Some races don't know how to create money, where as some flurish at keeping the going rate of it high.
You could implement something in game where the currencies are connected to real-world. Have the Human currency connected to 'Euros'. Dark elf currency connected to 'Pounds'. Have the values reflecting real-world currency. But I am thinking that is flawed as well. The game should balance and reflect what the currency value is not the real-world.

Just a couple more ideas to toss out there!

This would do'able if you were able to keep limit the amount of the resource (ie..rare metal like gold/silver/plat) and keep track of how much is in player hands.

And then the inability to DESTROY currency. Like gold and steel these days, it never really ever goes away, just melted down and reused.
