I've been looking at my Vitros, which don't get much attention in my house, and I've been comparing what I had separated as White Blackies and Black Whities. This separation was initially based primarily on the lots that the marbles came in - a lot with many Whities and no Blackies, or vice versa, would land the black-ribboned marble along with the rest. And these marbles do appear more at home in one group than the other. It seems that the white base on Blackies is not as bright as that on Whities, and as far as I can tell, the black ribbons are often more thinly applied on the Blackies as well. Does anyone else have other suggestions? Would any one have an idea about the relative numbers of these produced?
Thanks,
