Coins have the shape of an octagon. There is a thick golden border around the coin with marks on it. Inside the octagonal border is another octagon, but it is dark brown. There is a golden square inside the brown octagon and another lighter square inside the gold square.
Coins can be found in almost every level. They do not give the player any points when collected. Coins collected in a level will appear transparent when the player revisits the level, indicating that the coin has already been collected and recollecting it will not do anything. Collecting coins can allow the player to pass the multiple gates guarded by the Gate Keeper.
