Coin
From Project Rebearth
Coin is the currency of Project Rebearth. It is generated by town buildings, market stalls, and the Taxation choice, and is consumed as upkeep by Towers, Water Towers, and research buildings. Unlike standard resources, 
Coin operates as a separate currency and is not held in Warehouses or other storage buildings. Running out of Coin triggers the Bankruptcy event.
Production
[edit]Several buildings generate Coin at a fixed rate, regardless of biome.
| Building | Coin Rate |
Input | Notes |
|---|---|---|---|
| Square | +1/day | — | Upgraded Center |
| Market | +1/day | — | Trade hub |
| Tavern | +10/day | -10  Drinks/day |

The Tavern is the most efficient single-building source of Coin, converting Drinks into Coin at a 1:1 ratio. The four food-based market stalls (Meat, Fish, Bread, Vegetable) each produce only +0.05 Coin per day, while Market Stall Goods produces +0.5 Coin per day by consuming Clothes instead of Food.
The Taxation choice enables per-inhabitant Coin generation across the town. It requires 100,000 
Knowledge to unlock, has a 1-day lock, and permanently reduces Happiness by 30%. Once active, taxation efficiency is further modified by alliance types: the Trade Alliance increases it by 10% (×1.1), while the Great Federation decreases it by 20% (×0.8).
Production Chains
[edit] Coin sits at the end of several conversion chains. It cannot be refined further and is consumed directly by buildings or spent in trade.
Tavern Chain
[edit]The most productive Coin chain. 
Grain fields supply the Brewery, which converts Grain into Drinks at a 1:1 ratio (-50 Grain/day, +50 Drinks/day). The Tavern then converts Drinks into Coin at a 1:1 ratio (-10 Drinks/day, +10 Coin/day). Each Tavern requires 5 workers.
Market Stall Chain (Food)
[edit]Food-based market stalls convert Food into small amounts of Coin (+0.05/day each). The Food can come from any source, including fields, fisheries, or processed via the Bakery or Creamery.
Market Stall Chain (Clothes)
[edit]
Market Stall Goods converts Clothes into Coin at +0.5/day, ten times the rate of food-based stalls.
Consumption
[edit]| Building | Coin Rate |
Category | Notes |
|---|---|---|---|
| Tower | -5/day | Defense | Territory expansion on land |
| Water Tower | -5/day | Defense | Territory expansion on water |
| University | -10/day | Research | Also consumes -5  Glass/day; produces +10 Knowledge/day
|
| Museum | -10/day | Research | Produces +5 Knowledge/day
|
Towers and Water Towers each consume 5 Coin per day. Universities and Museums consume 10 Coin per day each, making research buildings the largest single drain on Coin income. Maintaining a positive Coin balance requires careful scaling of production buildings relative to defense and research expenditures.
Construction Cost
[edit]One building uses Coin as a construction material:
| Building | Cost | Category |
|---|---|---|
| Park | 50 Coin |
Decorative |
Storage
[edit] Coin is not part of the standard storable resource pool. It does not occupy space in the Center, Square, Warehouse, or any other storage building. Coin operates as a separate currency with no storage cap.
Trade
[edit] Coin is the medium of exchange in the trade system. Players use Coin to purchase resources through the Market (1,000 trade capacity) and the Port (5,000 trade capacity). Export and import costs are modified by trade focus choices:
| Choice | Export Cost | Import Cost | Lock |
|---|---|---|---|
| Export Focus | ×0.85 | ×1.2 | 14 days |
| Neutral Focus | ×1.0 | ×1.0 | 14 days (default) |
| Import Focus | ×1.2 | ×0.85 | 14 days |
The Trade Alliance also reduces both export and import costs by 10% (×0.9 each).
Affected By
[edit]The following choices and effects influence the Coin economy:
| Choice | Effect | Multiplier | Notes |
|---|---|---|---|
| Taxation | Enables per-inhabitant income | — | Costs 100,000 Knowledge; enables taxation; -30% Happiness; 1-day lock
|
| Trade Alliance | Taxation efficiency | ×1.1 | Alliance type; also reduces trade costs ×0.9 |
| Great Federation | Taxation efficiency | ×0.8 | Alliance type; also boosts production ×1.1 |
| Export Focus | Export cost | ×0.85 | Import cost ×1.2; 14-day lock |
| Import Focus | Import cost | ×0.85 | Export cost ×1.2; 14-day lock |
Bankruptcy
[edit]If Coin balance reaches zero, the Bankruptcy event triggers. During bankruptcy, Towers deteriorate and are eventually destroyed, causing loss of controlled territory. Preventing bankruptcy requires maintaining a positive income through production buildings or reducing consumption by demolishing Towers and research buildings.
