Well I guess I better keep all the ones I have in case they become an expensive collector's item. Just like the benie babies

Beanie babies never did reach their expected potential. Some are worth a small fortune but it's mainly the rare ones.
Currency is always collectable though, when the US gets rid of pennies I assume after a while you'd make a good return on investment. Though you'd want to look for error coins or coins in the best condition. Maybe they could be a family heirloom? In a generations time, they could be worth a small fortune.
