Embossed star coins from Super Mario 64 have many uses!
Print out a bunch of yellow ones and use circles of them to mark the warp zones and other secrets in your house!
Print out 8 red ones and place them in a platformy area of your house and award a star to anyone who finds all of them!
Print out some blue ones because blue coins are cool!
NOTE:
Printing 100 of them will not grant you an extra life.
Coins cannot be used as an underwater breathing apparatus.
Coins will not heal any injury.
Coins are legal tender only in the Mushroom Kingdom, and may not be used for any debts outside of the Mushroom Kingdom, including, but not limited to, cake purchases, yellow rabbit traps, or stolen hat insurance.
