The photos above make the coin appear dipped, the photos lack luster, and TwoHawks is right on you can't have cartwheel effect if the coin is PL or DMPL. Just my 2Â¢ worth.
I'd offer the potential buyer a full refund if he is not satisfied after the coin is shipped to him. Explain you are not a photographer, you may want to try shooting the coin outside in natural light, many compact digital cameras work much better if the lighting is sunlight, looks like the white balance on your camera is confused, and you may be shooting in an area of mixed lighting, incandescent, fluorescent LED, Halogen, colors appear strange when a camera tries to come up with a good neutral tone in mixed lighting.
Coming from a pro photographer of a couple of decades, lighting balance is one of the hardest things to deal with, especially in the days of film. If your camera offers you a way to shoot in RAW format, try that, many image programs will let you adjust the white balance afterwards in software that way, I know my Canon does and Nikon as well.
