The darkness is just because i didn't have enough light on the pic. It's a really old ANACS holder. PF-63.
Very hard to tell by the pics honestly. Could you try some other pics? But what I can tell from the pics it looks like the coat has some weakness in it of the frost, (basically just not enough there IMHO) which would keep it from grading a cameo. But better pics would help more. Phoenix
It wasn't graded as a cameo because it isn't. See the way the light reflects off the bust - all bright and shiny. If it was a cameo that would not happen.
