Here we have 13 Vtg Vitro Agate Marble King 5 and 6 Vein Cats Eye Yellow Orange (1 with blue on veins) Red Hybrid Marble Job Lot- marbles are approx 0.613”. There is one 6 vein yellow with red hybrid cats eye marble, the rest are 5 vein. The orange marbles are hybrids, however the color on the edge of the veins is very faint. Marbles are in good condition with signs of normal, minor wear from use and storage, however there are some marbles that have some small chips/ scratches in the surface (there are some that have more wear than others, some imperfections may be a pontil mark or some other sort of manufacturing defect) as seen in pictures. Please see pictures for the exact item you will be receiving and please check out our other vintage antique items. I am not 100% sure of this marbles maker or of its exact origin as I am not an avid marble collector. So I am trying to make my best educated guess by what I found, if you know the exact identification of any of the marbles I list feel free to message me as I don’t want to wrongly identify any marble so any help is much appreciated.
