I am going to work on a paper currency for H&H. Simply put, it's a piece of parchment with a code written on it, and it's worth in copper coins. Here is how it will go down. I am working on a code system that would be hard to figure out, and hard to counterfeit. To check if a note is real, you would go to a little website thingy where the codes for all bills are stored, and if it's a match, you have a real Herthian Dollar. To make sure there is no inflation, I am going to use the ancient chinese method. You turn in your coins and receive the same amount in paper money, and the money is stored there in case you want to get the metal coins back.
The problem is that it would require one hell of a vault to keep away thieves. I'm thinking a copper mine surrounded by 2 layers of brick, and then as much palisade as I can. Then the coins would be stored inside the mine. On each parchment it will say something like "100 Hearthian Dollars - (code here)" 1 Heathian Dollar is 1 copper coin.
What is the going price, in copper coins, for one piece of parchment? Because that would have to be added to the dollar to make sure the cost of parchment doesn't fluctuate to bad. What do you guys think? (I got the idea from my friend you guys know as Farm Champ, who used to play H&H.)
