I don't think there is a name associated with it and the more I look at it the more Vitro it looks to me, so I don't know what to think about it, other than that it looks like a veneered marble.
Sorry, not much help, I know. lol
It's a slag. Are there any cut lines that you can see? The large, sort of oval, reflection that covers the top half of the marble in every pic makes it hard to see if there are - the reflection itself can look like a seam.
Thanks, Ron. I guess it's the fact that on all of these packages the term "old fashion(ed)" is used and if the marbles had just come off the rollers that might seem a little odd, or maybe not.
That's an interesting bag. It sort of looks like it might have been packaged around the same time as the PB poly bag with the extra header card, like the one you show. DO you know anything more about them?
