How to convert coins into paper money or deposit coins into bank account, without your bank in local?
Ask around your area. Some stores will exchange because it saves them having to go to the bank to stock up on change. Some stores have machines that will convert the coins for a small percentage fee.  Some banks may do this exchange for folks who aren't customers, though that's uncommon.  My solution was to open a small account locally specifically as a place to dump my coins into. They'll even run a pile of coins through their counting machine for me, free, so I don't have to make up coin rolls as I did in the past.
