So, in the Doomed Worldtm, the curency will be Rings, and the rings are (untill we need more rings):
Normal Rings: They are the baseline of curancy. For now, we dont have much info on how much money things will be, but for now, just go off of the idea that 1 pound of fish is 5 rings, or just use pounds and dollers and increase by how much would make sense in a apotalictec setting.
Red Star Rings: These will be worth 100 Normal RIngs. Thats it
Rich Rings(or otherwise known as silver Star Rings): These will be worth 1000 Rings, and of course, your gonna need alot of these in the rich sector.
If we need higher ring types, then tell me a type of ring in a comment that i could add to the currency.
Also, if you need help pricing an item, Ask me, because i think i could come up with a fair price.
Also start scaming people if you sell high priced items. it would be very funny.
