Internal Reject Bin?

My guess is you didn't break it, you jammed it. Just like when paper mis-feeds into a printer. You have to open it up and physically remove the item causing the jam.

In de la rue machines (the company that makes most coin counting machines), large size dollars (and anything else much thicker or bigger than a half dollar) get stuck in a rotating collecting basin that is immediately beneath where you dump the coins in. The dollars are to big to move on to the sorter mechanism so they just keep floating around in the collection basin until someone cleans the machine. If you know what your doing you can fish them out with your fingers when the machine is running, but I wouldn't recommend it unless you've worked with such machines before professionally. I've pulled dozens of them out of machines personally as well as a Morgan silver dollar and various foriegn coins some silver (like those big 10% silver mexican pesos).
