The main currency used around the world is known as a “chip”, a large coin made of a high-quality clay or resin and stamped with the number of the Green that the coin came from. The Church is responsible for the minting and distribution of all coins.
One chip is approximately enough to sustain one average human for one day. The coins are most often used to redeem daily rations from one of the many churches spread across the world. Most non-skilled laborers will earn about 1 chip per day, while skilled laborers might expect to earn 5 chips per day.
Most merchants and nobles will not earn “chips per day” by virtue of their lofty position; most of their concerns are taken care of by their rank in society. However, a rough estimate of 20 chips per day will do for most low- to mid-level merchants and nobles.
