I use the debit card more so the change is moving slower. I filled the 5 gallon water jug like you have. Wife rolled it in the closet. I have a few other gallon containers full. Not sure what to do with it besides cash it in.
I have a couple credit unions here that take change. It is like an ATM machine. You put your account number in and pour away. It is an automated counter. No charge for bringing in change. I have seen the ones at walmart charging 10% ouch.
Congrats... It takes quite a while to fill the big jug.
I was wondering if it was worth it to go through the jug to see if any of it are silver coins.
