I thought you had to bring them rolled? That's what I've always been told. You can get the casings for rolled coins really cheap, though.
My credit union makes you unroll them. I guess people were sneaking in fake coins. Now they have to be unrolled and counted by the machine.
More and more banks are requiring you to roll your coins first, which means you have to count them to make sure they're accurate.
Many Coinstar machines will give you the exact amount of money you put in but in Amazon credit.
My credit union has a free coin counting machine.. But that's a credit union.
