Yes, the star wars world is fascinating, but don't bother too much with its monetary system. It's chaos there, not even anarchy (are not the same) and any currency will not survive.

Only Darth's coin is unique. There's only ONE coin in existence and that is mine (pure scarcity). Forged in lava from Mustafar planet, with a secret scarce metal. The darthcoin can't be transferred to somebody else.
