Feedback:User/Robot/Zaishen Coins

Zaishen coins as you know go from copper to silver to gold, but what if you transfer up to gold, and decide you want something from silver or copper, there is no system to revert from gold to silver to copper. my suggestion is to enforce a system to make gold to down to silver and copper, or another system to buy things in a bundle, such as bundles of 5 for tomes etc etc.
