1908 Barber Dime - PCGS

Bad news
Don't work too well on NGC.
Takes about 3 coats to work the best.
The scratches on the slab were to hide the mark on the back.

Good news
Takes about 85% scratches out with three tries.
Takes maybe 15% scratches out on NGC with 3 tries
Not too expensive.

Your welcome Dave. But I been thinking of having my friend send it for CAC. You think that's a much better route?

But for anyone who wants to try this must use a 100% cotton cloth. Otherwise you will scratch the slab. I picked up a kitchen 100% cotton cloth for $1.98

When applying the stuff, it's recommended to use gloves and avoid contact from skin. It will make your skin feel likes it's burning. I learned my lesson.
Also you must wear a mask to prevent from breathing it in.
Or will cause headaches. Once you wipe the stuff off, it don't seem to have any risk to cause health problems.

I will be putting some more on to take that light scratch out from the front.
