You can get to the magnets in a Coinstar machine. Many banks use similar machines, but of a different brand. These usually have a visible magnet you can snag coins from. In a Coinstar brand machine, there is a reject area towards the bottom of the machine. Coins are sometimes in there left by people who leave them on purpose, or don't know that there were coins rejected. Also, especially if you are younger (like me!), you can look under the machine. That is where I found my silver coins. Many people see rejected coins, and just decide to put them under the machine to not worry about them (This is what I think happens, some of it could also be dropped coins). It would probably go in the trash if there were trash can around the Coinstars here.
