it doesn't appeal to me the way $9K does, but it's all subjective.
re: pontil, flat spots, condition, etc: agree that there are a few things that are unusual (making it an unusual marble).
Some of the later German handmades don't have the same fit & finish on the pontils as the earlier ones. I 'm saying later due to the bold colors. There aren't too many examples of later ones I've seen in this size
Big marbles like this would be hard to handle and tongs could have been used, unfortunately making indentations or flat spots. The large size (mass) is also prone to deforming, cold rolls etc. My understanding is a wooden tool was sometimes used to make it more of a sphere which helps the shape but not the low areas like cold rolls and indentations.
I've got no skin in this game so merely my 2 cents for what it's worth
