Numismatic Overhaul Wiki

Vanilla trading runs on a single green gem. One emerald buys a loaf of bread and one emerald buys a diamond pickaxe, so prices never really mean anything and a villager hall turns into a pile of identical stacks.

This mod swaps that for real money. Three coins of different worth circulate, villagers quote their prices in them, mobs and loot chests hand them out, and you carry a running balance instead of stacks of change. On top of that you can set up a shop of your own and let other players buy from it while you are away.

There are three denominations, and they convert at a flat rate:

Any amount of money can be written as at most one number of each, the same way real change works — 12,345 bronze is 1 gold, 23 silver and 45 bronze.

The coin icon changes as the stack grows, so you can read roughly how much is in a slot at a glance: a lone coin, a small handful, a heap, and a full pile all draw differently. Coins stack higher than ordinary items, and dropping one stack onto another of a smaller denomination merges them into the larger coin automatically.

You do not have to carry coins in your inventory. Every player has a purse — a single balance that travels with them.

A small pouch button sits in the corner of your inventory screen, the creative menu and any trading screen. Click it to open the purse, where you can:

• deposit every loose coin in your inventory in one click, or
• withdraw an exact amount by dialling in how many gold, silver and bronze you want.

The purse is the account trades draw from. When you buy something and your hands are empty, the price comes straight out of your balance, so you never have to count out change at the counter.

A Money Bag packs any amount of money into one item. It is useful for three things: paying a price too large to fit in coin slots, handing someone a lump sum, and storing wealth compactly.

The bag's appearance changes with how much is inside, so a small payment and a fortune are easy to tell apart on sight. Right-click a bag to tip its contents into your purse — the bag is consumed and the balance goes up.

Expensive shop offers are priced in bags rather than coins, because a single trade slot cannot hold enough individual coins to cover them.

Villager and wandering-trader prices are rewritten the moment their offers are generated. Anywhere a trade used to ask for emeralds, it now asks for coins of equivalent worth, and anywhere a villager used to pay you in emeralds it pays in coins instead.

Because the conversion happens to the offer itself, this covers professions added by other content as well — if it produces an ordinary trade, it gets priced in coins like everything else.

The purse button appears on the trading screen too, so you can top up mid-transaction without closing the villager.

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.

The Piggy Bank is a small container built for money. It holds coins and shows three slots — one for each denomination — with a faint hint icon in any slot that is still empty.

Getting your savings back out has two routes, and they are deliberately different:

• Break it with a tool named Hammer in an anvil, and the block drops along with everything inside, intact.
• Or drop an anvil on top of it. The bank shatters with a satisfying crack, coins burst out across the floor, and the block itself is gone.

The second route is faster and far more fun, but it costs you the bank.

The Shop block turns you into a merchant who does not have to be present.

Place one and it belongs to you. Right-click it as the owner and you get the management screen: a stock grid on the left where you put the goods you are selling, and a panel on the right showing the takings that have piled up, with three fields for withdrawing them in gold, silver and bronze.

Set a price against each item you stock and the shop starts trading. Anybody else who right-clicks it sees an ordinary merchant screen — your goods on the left, your prices in coins — and pays straight from their purse. What they pay collects inside the shop for you to withdraw later.

A hopper toggle on the management screen decides whether hoppers may push items into the shop, so you can wire a farm directly into your stock. The Inexhaustible Shop is a variant whose stock never depletes, meant for servers that want a fixed-price outlet rather than a player business.

Two commands are available to operators.

/numismatic balance <player> get reads a player's purse.

/numismatic balance <player> set|add|subtract <amount> writes to it. Amounts are given in bronze, so 10000 is one gold.

/numismatic serverworth totals up the money held by everyone currently online — handy for spotting inflation on a long-running world.

A few things worth knowing:

• Your purse balance is stored on your player, so it survives death and follows you between dimensions.
• A Piggy Bank keeps its contents when you break it properly, and a Shop keeps its stock and takings.
• Villager trade prices are set when the offers are generated, so a villager you met before installing the mod may need to restock before its prices change.
• The conversion between coins and the old gem economy is fixed, which means prices stay comparable across worlds.
