I have a penny that stop my disposal from spinning, it is in between the teeth and wall, well I tried and tried to use diff things to remove it even duct tape on the end of a screw driver , didn't help :( well now with all the trying to get it out, it has been shoved down so far that I don't see it anymore.. I think it might be down inside maybe the motor? I'm scared to turn it on , but the thing seems to move freely if turned by hand.(already unplugged) , so hopefully you can fill me in on some thing's, like if I turn it on will it get lodge somewhere else?

Turn it on. It will either work or not. If it works, good. If not, you can put another one in. They sell inserts that prevent coins from going in.
