The present currency system really needs work with only one coin. On a server that used these as currency I quickly filled my chest with the credits . It would be nice if they stacked up to 100+.
It would also be great if their were like cents and notes. So 100 copper coins(I guess) makes 1 Industrial credit and then 100 makes a gold coin. 100 of these would make 1 iridium coin. This would allow you to have 100 iridium coins or 100,000,000 copper coins in one stack.
Another thing could be that the coins could be found in chests and be traded for emeralds with villagers. Maybe a few copper coins could be droped by monsters aswell
Thankyou, if you have any more ideas post them.
