As for the perfectly good dimes coming out, sometimes people dump the coins in too quickly and the machine jams and spits them out. Or, a mangled coin or foreign coin can get rejected and they come out behind it. I've found a few scoops of foreign coins if you go back in the thread. But no ancient Roman coin, although you did have an assist. Was this a coin star or a coin counting machine at your bank? Because coin star is supposed to account for everything in the interior reject bin. 3 dimes and a penny in the slot.
