I used MCreator to create this mod for my server and based some textures off of an old mod called Varied Commodities

Some Coins have special abilities:

• Copper - Stand to close to any conductive blocks with these in your pocket...
• Gold - Some times you feel lucky, others...
• Amethyst - Now hear me out, Flowers, maybe...
• Ruby - Trade XP for blood or blood for XP
• Diamond - Harden yourself
• Emerald - Villagers love me
• Netherite - Planes walking or just unlimited ender pearls

How do you get coins?

• You can find them from ores or flowers

How do I store these coins? they take up too much space

• Craft and ATM machine

How do I make x coin from y coin

• To make the next tier, it requires 4 of the one below it. So 4 Wood coins makes 1 Stone coin, and 1 Stone coin makes 4 Wood coins.

Coin Flower

The Coin Flower is very fragile, Touch it and it might break into coins.
However if you find a way to harness it's power without touching it, you can harvest coins from it. So long as it has the nutrients it needs.- -
