barrysloateI assume the card you refer to is the one in the upper right corner, and not the Dogs Head, which is clearly him (and a pretty scarce cabinet). They have certain threshholds about what they will or will not authenticate, and you just have to speak with them about it. Maybe they really don't know what Silver King looks like, and that is the issue. If you could prove it is him, that might help.
edited to say the Dogs Head is now gone.
