Celluloid Sepia Button Photo

I found a few celluloid button photos and just love these little guys!

Photo is mounted on tin and inserted in an original stamped tin frame. The photo mount has two slots in the back for an easel, the ribbon-like frame has a loop for wall hanging. The back has a stamp / mark for Columbia Photographic Co. Chicago. This piece is in wonderful condition showing no pitting, dents or cracks.

I am curious as to which holds a greater value; sepia or black & white?

Thanks for peeking!
