It has already been pointed out elsewhere that, in a world where magic is common, a precious metal economy would be quite impractical. The below system is an extreme simplification, but should make it relatively simple for characters to keep track of regular expenses.
100 brass coins (brass, penny, B) = 1 silver coin (silver, tear, S)
100 silver coins = 1 gold coin (gold, crown, G)
10 gold coins = 1 Quint-infused gold coin (quint, pawn, Q)
100 Quint-infused coins = 1 spiritually awakened coin (wake, eye, W)
I'm kind of cheating to make this easy on myself by giving a tear the buying power of a U.S. dollar. This makes it easy to gauge the prices of goods and services.
Coin | U.S. Dollar value | U.K. Pounds value |
1 penny (B) | 1 cent | approx. 1/2 pence |
1 tear (S) | $1 | 65 pence |
1 crown (G) | $100 | 65 Pounds |
1 pawn (Q) | $1,000 | 650 Pounds |
1 eye (W) | $100,000 | 6,500 Pounds |
