Give them to a homeless person and make their day!
I have an old purple pouch thingy that I put all of my leftover change into so that I can keep track of coins and save:)
But I was wondering if this is really good or not considering that the money is not building interest and just sitting around. The bank teller would not accept them when I gave them to her to deposit and said that I would have to sort then first (myself) and that seemed tiresome and risky.
Now I use the coins to spend at the laundromat but I wonder if they could be good for something else while there are still some left ( there is probably $5 left I think )
