I've been playing with my new camera trying to take pics through the slab Unfortunately the slab on the 1992-D is pretty scratched up
Nice work ziggy, remember it's all about the lighting. I've been using Meguiars product for cars called PlastX to polish out scratches on my slabs. It's a bit of work, but I have been successful in removing scratches over the coin.
Yes it's only about seven dollars at Wall Mart and my first bottle lasted a couple of years. Nice presentation.
I use Mother's plastic polish. I bought it in 1998 to refinish my Mustang's tail lights, and I still have the same bottle today. Works well.
