Am I suppose to do something with it, like the Wizard's Tokens? O.o

There's a coin machine in Centropolis that you can put it in and get a couple k sP from.

Or you could hoard them to hand over to the recycle beast when he asks for them. Slot items are quite frequently asked for.

I think I will hoard them. Thank you very much. =D

C: You're welcome!
