70s Japanese Cat's Eyes ?

[scott9109]

I was told these are old, and as some are light blue, I assume these are 60s or 70s Japanese.  The top left marble is a hybrid 28mm in diameter, the two horseshoe? pieces are cool, the yellow one having a large air bubble in the center. The one white 'banana' in light blue-green is also interesting.  The dark cobalt blue marble also seems unusual.  Thank you for any insight into these marbles.

Yes most of these are unsure about yellow and orange one on top left. And I think the one under the cats eye is vacor not 100 percent sure on this need more pictures

Thank you.  Yes, perhaps the cobalt blue one is Vacor.  The texture is oily and the surface is pitted orange peel.

Were light blue-green, 3 and 6-vein cat's eyes ever made anywhere other than in Japan ?

A lot of Japanese cats eyes have a marking on them not all of them either at the top of the cats eye or bottom of both.  These just look Japanese style a lot of American cats eyes core are different shapes and styles. I’m not even 100 percent on all your cats eyes being pre 1970s because there’s that many types of Japanese cats eyes. Some are easier to tell than others in my opinion. Maybe someone else with give you more detail in to these. Even if they are pre1970s not much value in them either way.

Thank you for your replies, Spn.  I'm new to this, but I really like them.  I will search today and try to buy a copy of Elizabeth Kempski's book.
