Other Info:
Each coin came individually packaged with a mini Game Boy-styled display cover, which is made of card. When the coin is placed correctly inside the cover, it looks like a screen from the game (see images below). I'm not sure how many coins are in the set but I do know that there are three different colour variations of each coin - gold, silver, and bronze.
