How do I turn my Coinstar coins into cash without a fee?

Excuse me, I'm wondering about a specific process. I have some coins from Coinstar, and I'm looking for a way to convert them into cash without incurring any fees. Could you please provide some guidance or insight on how to achieve this? I've heard there might be certain methods or options available, but I'm not sure exactly what they are. Could you enlighten me on the best way to go about it?
