This add-on adds:
- 6 main types of coins
    -Copper Coins

    -Iron Coins

    -Gold Coins

    -Emerald Coins

    -Diamond Coins

    -Netherite Coins

Each coin is crafted using its respective resource, and 3 pieces of paper in a shapeless recipe. Once ingots have been crafted into coins, there is no going back. They will remain coins forever unless destroyed.

And they can be upgraded or downgraded to the other coin types. For example, 9 Iron Coins to 1 Gold Coin, or 1 Gold Coin back into 9 Iron Coins.

Coins can also stack onto each other to help prevent inventory clutter! Simply put 4 of any coin into the crafting table to make a stack, or use 4 stacks to make a pouch!

Each coin type is worth 9 of the previous type of coin, meaning each coin is worth exponentially more than the last. For example, the Netherite Coin is worth 9⁶ Copper Coins. That's  534,441 total Copper Coins!

Mob Coins have been added as well! Most Monsters now have a collectible coin that they can drop! However, these coins are very rare.
 

Each collectible coin also has an exchange rate, if collecting isn't your thing.

The image below shows everything new added in the update to 1.18.

For those of you who don't like being able to craft the coins, a second version of this addon has been made which removes the ability to craft coins and collect mob coins.
