Most modern banks have coin counters, In fact most of them I have delt with for returns wont take em rolled, they have to be lose so they can run them though.
Some banks will take hand rolled no questions asked if its a small amount, if you go in with 2 penny rolls 3 nickels a couple dimes and some quarters they are most likely going to figure you checked. If its off a bit its off a bit.
Some smaller and less busy banks roll all there coin machine coins them selves. It depends on how busy the place is. A busy bank will send off the lose coins to the fed for machine rolling and pay the fees.
A less busy bank that has tellers with nothing better to do will have them roll coins when its slow to better utilize them as an asset.
Some banks are very anal and require an account number on hand rolls so if it is off they can debit your account.
But most busy banks accept the fact that no matter how careful you are you will always have a balance sheet off by a bit, it just happens. Anyone who has worked as a cashier knows this. Human error dealing with lots of money will make a balance off a few coins or dollars. So long as its very close its what matters.
Also as a courtesy I would not take coins you got from your bank back to the same bank. It does cost them money to order boxes, and it also costs them money to take them back in. Best to get coins from one bank that you can work a good repore with, and then after searching take them to another bank with a counter so you dont have to re roll them, working with multiple banks works best as it does not draw too much attention. The last thing you want is everyone in your community doing the same thing, that would put a crimp down on CHR real fast because banks can say no.
