Sometimes it depends on the specific bank you are going to (not the franchise, but the specific branch), so I would recommend asking each bank and letting then know you want to make it as easy as possible for them. At some banks, you have to dump coins, they won't except rolls or loose. Some larger banks want the coins in bags. Really the best case is when a bank will take the re-rolled halves in the box, since this is very easy for the tellers. I re-roll right in the same rolls they came in, it's slow at first but then you get quick at it. Unfortunately, some banks won't take re-rolled boxes because they say they can't verify what's in them. So really, it depends, start up a quick conversation with the tellers and find out what's best for them.
