So I found this spare part from who knows what and tried to think of what it could be, and I came up with Kerbal money! The way this not complicated system could work is that the height of the bottom ring determines how much it's worth and the upper ring determines how much it's multiplied by. So, after that awful explanation here's how much this one's worth: 20 funds, yeah not much. You can tell it's 20 funds because the bottom ring is twice the height of the top one (2) and the top ring has 1 flat side (x10) so it's 20 funds. The max value of a Kerbal "coin" is 50000 funds (bottom ring is 5 times the height of the top one and the top one has 4 flat sides.) So, feel free to tell me what you think of this very Kerbal idea for the currency (putting the value of the coin on the coin in number from is so lame.)
