The coin counter or bank bagging it to be sent off and counted is essential IMO. It saves a ton of time rerolling. Just make sure you at least know approximately what you have, so you can argue if you get shorted by too much. I got lucky when I set things up at my current dump bank, one of the tellers knew exactly what I was doing and why when I asked "Do you know why I have so many half dollars?" when I had a backpack with about $584 loose. I put those in the machine, but then found out they can be bagged and sent to HQ to be counted and have since done that. Half Dollars are kind of rough on their machine, especially in the quantity I would bring, so I do that to avoid getting cut off from dumping there. I even shot the teller a friend request on Facebook and she accepted.
