Gather Copper Ore
Locate copper ore in the Overworld, typically found between Y-levels 0 and 96. Mine it with a stone pickaxe or better to obtain raw copper.
Smelt Raw Copper
Place your raw copper in a furnace or blast furnace along with fuel (coal, charcoal, or wood). Smelting produces copper ingots.
Craft Copper Coins
Once you have copper ingots, open your crafting table. Arrange the ingots according to the mod's 
copper coin recipe to create your first coins. Copper coins represent the lowest tier of currency in the mod.
Store and Use
Keep your coins in your inventory or storage. Copper coins are ideal for small trades with other players or as a starting point before working toward higher-value currency tiers. You can stack multiple coins together to accumulate wealth for larger transactions.
