Ultra Greed Coins are enemies exclusively spawned by Ultra Greed during some of his attacks.
Spinner Coins will spin around the room. Unlike the other coins, these deal contact damage, but won't do anything if they are not destroyed in time. They also last longer.
Key Coins open the golden doors around Ultra Greed's boss room if not destroyed, which spawn hordes of Greed Gapers.
Heart Coins heal Ultra Greed for 13.125 HP each if not destroyed.
