Numismatic Coin Addon is a lightweight addon for Numismatic Overhaul that adds new Minecraft-inspired coins designed for economy-based servers.
The mod expands the existing currency system with Emerald and Diamond coins, giving servers more options for shops, player trading, large balances and custom economies.
The goal is simple: extend Numismatic Overhaul with additional currencies that are easy to integrate into a modded server and consistent with the Minecraft universe.
Numismatic Coin Addon does not replace Numismatic Overhaul. It keeps the original Bronze, Silver and Gold coins unchanged and adds two higher-tier coins above Gold.
Coin Values
Numismatic Overhaul already uses the following base progression:
- 100 Bronze Coins = 1 Silver Coin
- 100 Silver Coins = 1 Gold Coin
Numismatic Coin Addon continues the same 100:1 progression with two new high-tier coins:
- 100 Gold Coins = 1 Emerald Coin
- 100 Emerald Coins = 1 Diamond Coin
Full currency progression:
- 1 Silver Coin = 100 Bronze Coins
- 1 Gold Coin = 100 Silver Coins
- 1 Emerald Coin = 100 Gold Coins
- 1 Diamond Coin = 100 Emerald Coins
Internal value reference:
- 1 Emerald Coin = 1,000,000 bronze value
- 1 Diamond Coin = 100,000,000 bronze value
Emerald and Diamond coins are intended to make large amounts of money easier to store, convert, display and manage, especially on economy-based servers and modpacks.

Notes
Numismatic Coin Addon does not replace Numismatic Overhaul.
It extends it with additional coins made for servers and custom economies.
It is especially useful for servers, shops and modpacks where Gold Coins are no longer enough to comfortably represent large balances.
The addon keeps the original Numismatic Overhaul currency structure intact and simply adds Emerald and Diamond as additional high-value tiers above Gold.
