Disclaimer This is not a real coin it is a metal replica, Thank you for stopping by. You are looking at a custom made Jeep Gear Shift Knob made from a Standard 2&1/4 inch diameter pool ball that I have inlaid the Morgan Silver Dollar 1871 replica coin into the top. This was made with a solid black 8 ball but if you desire another color just ask. I can make this for almost any application with a manual transmission, If its not one of the jeeps listed all I need is the thread size. I can also make them for reloading presses Like RCBS, Hornady, Dillon and others
