I would keep those two seperate from the others. If a blacklight illuminates them they're old-timers. I don't think any of today's marble manufacturers make those kinds of marbles. If anyone knows differently I'd like to know so I can buy some.
jabo marbles often glow....they use burmese glass from fenton....and many of the experimental runs of recent...shoot me a pm if youre lookin to get some for your collection....
