With Custom NPC:

When I make a Shop on an NPC and place the coins, this happens:

An apple worth $ 500, I can buy it with a $ 0.01 coin.

Do all the coins have the same ID or something similar? For this to happen it means that Custom NPC identifies each Bill / Coin as the same Item, but it only has a different name / texture.

Apart from the opposite, the item costs $ 10, and I have $ 20, he lets me buy it, but he doesn't give me change (Logic, Custom NPC is not programmed to give change), but would it still be solved if each ticket were a different item?

For example: If I don't have the $ 10 bill, it won't let me buy it.

It's the best Currency Mod by far, but this basically forces me to look for another option ...: S
