i like to make lots of custom potions in minecraft and i would put them into a trading system i like to do that alot but some times i don't know what to use for them as currency i like them to trade valuable stuff. some times i would make a custom item and use that in the trading system too but i need to know so that i don't use that item.

also please give me ideas for more potions if you leave an idea ill make that and ill put it in the big chest im putting everything in.
