Hrrm, different from our system. They might not have to deal with inflation. If a base unit coin is set to something like...an egg then there would be no inflation even if more coinage is made. It's like using a chit/stamp/ticket system. If one stamp is the cost of a meal, then everything is based on that value. Inflation...I need to check to see what was worth 1¢ back in the day when it first came out.
