Event token

Event tokens are special green coins that appear during certain events in Mario Kart Tour, starting with the Wild West Tour. Event tokens appear in all courses in a tour, where they replace several of the normal coins in a random manner. They can also be obtained from item boxes, from other drivers who have gotten hit, and from the Coin Box Special Item. They can then be used to purchase items from an Event Shop that is similar to the normal Shop, though items that don't appear in the normal Shop appear in the Event Shop, such as points-cap tickets and rubies. Players can only have as much as event tokens as needed to purchase all of the items in the Event Shop, after which they will stop appearing on courses.

Event tokens are very similar in appearance to the Bonus Medals in Super Mario Run, having a similar Super Star design on them.
