Regional coin

Regional Coins are one of the main collectibles in Super Mario Odyssey. They are purple and can be used to buy outfits, stickers and souvenirs. There are 50 or 100 located in most kingdoms, and their shape and design vary in each kingdom. After being collected, they are replaced with clear replicas which are worth 2 regular coins. The Cloud Kingdom, Ruined Kingdom, Dark Side, and Darker Side do not have Regional Coins.
