Earning Coins in Numismatic Overhaul

Money enters the world in three ways.

Killing mobs. Certain hostile mobs carry money and drop it when a player kills them. The amount varies a little from kill to kill rather than being a fixed number, so income is not perfectly predictable.

Loot chests. Coins and Money Bags generate in the treasure chests of strongholds, bastions, pillager outposts, buried treasure, dungeons, mineshafts and desert pyramids. The richer the structure, the larger the sum.

Selling. Villagers who used to hand you emeralds now hand you coins, and other players can pay you through your shop.
