Tired from diamonds, emeralds, irons economy? Don't worry here is your new currency, a texture pack that will add a new texture so you can use it in your economy!
I have also made a data pack for it so you can craft it in survival and you don't need to command for it but I failed. Then I thought there will be a great team with this resource pack and shopkeeper plugin which is available in aternos server or maybe also available in other servers plugin.
So you just need to command /give @p minecraft:paper[minecraft:item_model="money:X"]
Here "X" means:
1, 2, 10, 20, 50, 100, 200, 500, 1000, 5000, 10000, 50000, amathyst_coin, copper_coin, iron_coin, redstone_coin, gold_coin, emerald_coin, diamond_coin, netherite_coin
Enjoy your money life in minecraft...
