Shit. I would throw a pair of duckbill, needle nose clamps, vise grips, a dolly and couple hammers and maybe a small propane torch and go to town. What's the worst that could happen as long as you go slow and steady. Start on the least rolled side and walk it out. It might be perfect but you will have something to work with. If you don't like it then hammer it back. If you damage the paint the chrome will cover it. Just don't pry against the outer shell of the quarter.
