Coins

Coins are a feature introduced in Call of Duty: Mobile Zombies. They come in the form of miniature coins that can be gained in-game for 500 points, and used to grant the player a temporary power that benefits the player. They are extremely similar in function to GobbleGums from Call of Duty: Black Ops III.

Within the game, there are various different coins that grant different abilities. Coins can be acquired for 500 points, one at a time. Coin machines, or "Slow Play" machines, can be found across the map, with each being able to dispense Coins.
