I think these are kinda neat - frosted clear 3/4 in with large bubbles

This pair showed up in a mixed lot. I have moved them from here and there and just can't seem to stop picking them up again and again to take a look. So I am not a big fan of clear marbles except for nostalgic reasons but these rather oversized bubbles grab me.

I don't remember seeing another like them. I don't see any seams. They are not heavily frosted but certainly not clear. I guess I could ask if anyone else has any and if anybody knows where they came from. I wouldn't be surprised to find one in a spray paint can. They are hard to photograph.

Ummm-- 3/4" in a spray can would be over kill for sure. The smaller the better in shaking it up.

I would lean towards a Vacor of some type.

@Melissa may have a clue here--but this is a hard one to ID.

Nice try on the images--some of these frosted ones can be a bitch to image in a good way.

It may just be a commercial made marble, made for polishing something other than glass.

I appreciate all opinions and hope to see some more.

Marble--On!!
