Coins are an interactable item type in Monaco. Coins are randomly placed at the start of each level, and may sometimes be placed inside other interactables. Each coin missed upon completion of each mission adds ten seconds to that mission's score. For every ten coins found, each player gains another use of their tool. The Pickpocket's monkey, Hector, has the ability to collect coins at a distance.
Civilians, safes, and cash registers all carry coins.
