Seed Pearl Necklace and Bracelets

[Steve]

I've reposted the image of the daguerreotype. I have a question that might seem odd at first, but I want other people's opinions. Do you think the man is wearing a hairpiece? I ask because looking at the photo and you can see graying hair on the man's beard and to left side of the man's head over his ear (left side of the viewer with the man's hand holding the cane, it'd be the man's own right). You can see the gray go up to the top from that side on the back but the front center of the man's hair has no gray. The right side may or may not have gray, I can't tell if the lightness in the hair comes from the light source or not.

I'm not making an argument one way or the other yet. I just want other people's opinions. Am I seeing something that's really there or is it just an illusion?
