The standard currency of the world is the "Geldrin". Each nation mints it's own version of the Geldrin in 1G coins, 5G, 10G, and 20G paper bills. The standard exchange rate between the nations is: 0.8G to 1G, meaning that for every 1 Geldrin you exchange, you only get 80% back in equivalent exchange. The reason for this is that other nations do not value foreign currency as highly as their own. The only problem is that the reverse exchange does not apply, and therefore lost currency cannot be recovered. Most have come to accept this as an "Exchange fee" more than anything, and when people need to they exchange their domestic Geldrin or Mysidian, which has a constant exchange rate regardless of the country you are in.

Aside from the energy and other applications of Mysidian, the empires harvest and form the element into stones to be used as currency. Mysidian is used as a higher denomination currency valued at 10G per unit of Mysidian. Since Mysidian stones vary in size many people who deal with Mysidian regularly, carry a small scale, or at very least a caliper to measure stone worth. The most common stone size is worth the standard rate of 10G and is the basis for currency exchange, and is the size that is circulated by each of the empires. It is however, not uncommon to see larger Mysidian bricks valued at hundreds or even thousands of Geldrin. Each nation houses a reserve of Mysidian bricks for which the value of the Geldrin of that nation is backing; for every Geldrin there is an equivalent amount of Mysidian backing it at the reserve. When Geldrin is lost due to the exchange rate, the Mysidian which backed it is liquidated from the reserve and used in other non-economic applications such as the energy grid, or military, civic uses, etc.
