I think the Coinstar machines won't take a cut if you get a gift card to one of their affiliated merchants.
You could also just spend it a bit at a time. I use the coin acceptors in self checkout lines at the grocery store.
It may be worth making sure there aren't any silver coins in there (old dimes, quarters, half dollars, maybe others). They're worth more than face value and you can sell them at gold and silver brokers.
