I with you on that. I sent it to Marble Alan years back this is what he had to say.Hi Greg---I'm running late but am shipping your marble tomorrow. It measures 2-9/16" and is in 9.1-9.2 condition. The fact that there is minor damage in the way of microscopic flakes, a couple subsurface reflections, and some minor wear is suggestive of age; however, this could be faked if carefully done. Most large marbles like this will have ground pontils, which this one lacks. But it does have an abraded/filed basal pontil, which I have seen before on genuine examples. I hate to sit on the fence on this one because usually determining a fake for me is easy. This one is just too well done if indeed fake. But if real it's so incredibly rare I can't even begin to imagine how valuable it is...probably $3000-5000. Please get more opinions on it, Greg...I would like to hear what other seasoned collectors have to say! ~~Alan
