Gold'n coins
Gold'n coins is a mod that seamlessly integrates with vanilla Minecraft and adds economic features, particularly useful for multiplayer gameplay.
Banker - New Villager Type
The game introduces a new type of villager - the banker. Their workplace is the forging table. Most of the mod's items are obtained through trading with this banker.
The most important item available from the banker is the coin forging template.

This template can be duplicated using the following crafting recipe:

Coin Creation
Combine templates with golden nuggets in a forging table to create coins:

Each time you craft a coin, the template loses one durability point. The template has 50 durability points total.
Wealth Storage
For convenient coin storage, you can combine them into coin piles, and then into coin purses:

Trading Shops
If you want to sell your goods to other players, you'll need to set up a trading shop:

The shop can be crafted from any type of wooden planks, one wooden slab, a coin pile, and a gold block:

After crafting, the shop needs to be configured. Place it and select it using a wrench, which is easily crafted from gold and copper:

Using the wrench, select the shop you want to configure by right-clicking on it.
To set the price, hold the item that players should pay for your product in the required amount, and type "price set" in the chat.
For example: if I want to sell a stack of logs for 16 coins, I need to hold 16 coins and type "price set"
Then, to set the product, hold the item you want to sell in the required amount, and type "product set" in the chat
For example: if I want to sell my 64 logs, I need to hold 64 logs and type "product set"
Important: you can set the price in any items, not just the coins from this mod. It can be anything you want.
Pot of Gold
For base decoration or to showcase your wealth, you can obtain a pot of gold:

Currently, pots of gold can only be obtained through trading with a banker.
You can empty the pot by right-clicking to get coin piles, or fill it with coin piles.
If the pot receives a redstone signal, it will automatically empty itself, dropping coin piles.
This block is affected by gravity and can be mined with a pickaxe.
