I have 8 3-pound coffee cans full of change. Very standard mix collected over the past 20 years. I want to have somebody run it allthro3ugh a machine and give me cash or a check. The 2local grocery store charges 10% and a wholesaler that I used to buy pop for the machine will do it for 5%. My local banks don't have a machine. Isn't there a better choice? Any ideas who might have a machine and doesn't charge much? How much do you think is in those coffee cans?
