Really nice little marble. Looks like new inhand with a couple of little pops. Break out the loop and there are 3 tiny 1/2 moons and 1 tiny 3/4 moon. Nothing what so ever to take away from this little gem. 1870 or so. Never a reserve. 99p starting price. Please, no best offers. True marble auctions. Guaranteed I.D's and dates of manufacture to the best of known information. All measurement are done with a micrometer to the best of my ability. Please see detailed pics for condition. I t...ry very hard to show all aspects of the marbles surface. In doing so tiny little flaws end up looking quite monstrous, but that is my aim. Macro pics also show in vivid detail, makers marks, surface texture and ripples, surface debris, tiny bubbles and even their shadows in some pics. In your hand these details are much harder to see. Under-lit pictures show color and in some cases the transparency of the base. Some are just for fun. If you have any questions please feel free to ask. Combined shipping is no problem. Please wait for an adjusted invoice that should arrive right after the last auction ends. Happy bidding. *********** U.S POST OFFICE BOX HOLDERS PLEASE READ ********* INTERNATIONAL AS WELL ********* Royal Mail does not offer either "Signed For" nor "Tracked" shipping services to P.O Boxes.
