Usually people just throw the pennies away and leave it alone for it to collect dust. Are you the type of person that does that?
Or do you actually use it?
I'm more of yes and no, sometimes when I buy from a store they usually give me a few pennies so I just say "Keep the change" because pennies can accumulate in your pocket and I don't really feel like sorting it out.
Though, best way to get rid of pennies is to give it to children, they won't know a difference either way. They'll think of it as a toy.
