Back in the day I'd sometimes get "unknowns" in with a group of marbles picked up here and there.
My thought process (arguably flawed) would be to consider whatever manufacturers outside of the US were making marbles in a "similar" style to the OP, and where the vast majority were made (and where those countries exported to).
Just my opinion and not to take away from some good points already made.
Could be Vitro? I seem to recall a similar color combo on fancy conquerers...but the pattern on this is all over the place. and I don't know enough about them to be much more help
nice marbles! I've seen onionskins open up like that near end of cane so I'm not yet convinced it's buffed/polished. If original that's a very nice marble with the mica and all.
I think the term "end of day" is more of a myth when applied to marbles, although a fitting term for other types of glass manufacturing where you used up what you had left and made whimsy items (like turtles for example).
Alley was my first thought for both, although I don't know enough about these types of swirls.
And bummer on the Panther but there does look like a blue/white Pelt below it which might be worth a new post for comment
I for one, like to see some members posting again. Been a lot to learn over the years, and in my early days on the Forum, it's worth a thank-you for the knowledge that's been shared and gained during that time.
Awesome. Good on ya. I show some to my kids, nieces and nephews and explain briefly (attention span considered) and they go on their way. It's great when they come up with a creative game.
No need to apologize. My photo's are less than stellar . I meant more the lighting, and how the green appeared in a couple of those pics.
9" circumference then? That's a huge marble. Diameter would help narrow it down but I still wouldn't rule out MFC
No, the picture I was thinking of was from 10-15 years ago and some guy was describing his marbles as wet mint and (if memory serves) the oil bottle was in the background and dripping off his fingers
