I assume the top is a WV swirl. I'd guess Ravenswood or Alley.
Second is another WV swirl. Pretty sure Alley.
Any reason to think the aqua and brown is older? Because it looks like a newish marble -- a Jabo.
I can't tell how many marbles we're looking at after that point. Might be a Jabo in there. But one view which sort of looked Jabo has some older looking wear so maybe it's Champion.
I broke your other posts from this thread off into new threads so that it would be easier to discuss the marbles in those posts.
I think some kind of West Virginia Swirl.
(The question might have been between slag and swirl with those colors -- and I'm saying swirl.)
There were several companies who could have made it in the 30's through 50's. Others such as Ron ( @wvrons) might be able to narrow it down to one or two companies. I can't.
Welcome, Jen.
I so wish I had thought to rescue my dad's childhood marble bag before he decided that it was too worn to keep any longer. I knew about his bag before I started collecting marbles, but after I started collecting I let a few years lapse before it occurred to me to ask him about it, and when I asked it was too late.
Your green one has a good chance of being Master. Some small part of me wondered if it might be a modern marble which resembles Masters. But I think probably Master.
(Well, I mean your marble is a Peltier Rainbo ... which ever one it is that you think it might resemble. )
My avatar marble is a Dave's Appalachian Swirl.
Good chance of Jabo on the last one.
Need different views of the first one. If the ribbons stretch in a way that their ends might form a top and a bottom of the marble, then need those views.
The top might have been someone's favorite shooter! I can't tell what it is behind the damage.
The middle is a Vitro Tiger Eye from the 1950's.
The bottom is a West Virginia swirl. Many WV companies were making these in the 30's through 50's.
