Coins
Coins, gold, or gold coins, are a resource in Blue Prince. The primary use of coins is to purchase items at shops. They are almost universally referred to in-game using the 
icon.
As a resource item, they are frequently found in piles of up to five coins at a time, which can all be collected in a single action. Coins can be dug up from dig spots, found with a Metal Detector, or may have either random or fixed spawns in certain rooms. They can also be provided directly to the player by a range of effects.
