that's good a idea!

Make one into a piggy bank for her. Decorate it. Or, depending on how many you have, make them memento cans. Write a note to her every day until it fills up. Date the can and set it aside and make another one. Give them to your little one when they're an age you feel comfortable giving the gift to them. You can do this multiple times a day, too, and you can even put some pictures inside as a memory for you and them

yeah i use them for loose change but i have so many lol

I feel like there's some way we could make them useful! Like a DIY thing
