At homes we have too many coins left over after shopping, usually in the US we collect in a roll and pack it and go to the banks. Takes too much time if you have too many coins to roll in moneybags. Or there is Coinstar Coin collecting machines which are very convenient, you just drop all your coins and it sorts it out automatically.
But the problem with Coinstar, they charge close to 9% of the Total Value of the coins which is costly. So in order to avoid these payments, click the above link and click on a state to see cheap and free coin counting services in every state. More free locations will be added there. Many banks seem to have coin collecting machines that sorts automatically. I have to check the local bank next time to see whether they have such a facility. This free service will avoid the time to roll these coin bags. There is one Bank Atlantic in Florida and other areas, where they have free coin collecting vending machines.
