Sorry no idea on the marble I.D. mibber, obviously a manufacture incident of some kind wherever it came from. I was trying to narrow it down but I am lost. Yes !! I have to agree with you on taking pix of clear transparent glass marbles. When I was taking pix of my sulphides it was almost impossible to get focus on the glass surface and the figure in the center, "two different objects at 2 different distances" so the camera wanted to focus on one or the other & went back & forth. By complete accident I took a few "freehand" shots of them in my other hand, I was astonished, not only the surface but the figures inside as well. I'll post a pic so you can see, if you've ever tried to photograph a sulphide you know my quandary. Macro of the surface, no problem.
A luck shot of the barnyard pig with a non reflective gray background about 3 feet away, I was unprepared & upset when it showed so many reflections but the clarity was so good I decided to keep them, these handmades are very clean "not polished" all commons so I was really picky on the condition. I'm not really sure how I would do with showing any damage on a lesser specimen ?? I took at least 50 shots of different sulphides, different backgrounds, different colors and only kept 10 or 12 pix out of all of them. Marbles period are the hardest thing I've ever ran into to take pix of
