Very nice, V nicks are a favorite of mine.
Try using one or two LED flashlights with the LEDs off on the scope and any incandescent lamps off in the room. Position the LEDs at 180 degrees across and at about a 45 degree angle to coin surface. I use a modified scope setup, extended shaft to get full size coins, and two clip on LED goosenecks, works well for me, including getting the cartwheel luster effect. Works good on shooting through plastic too.
