I agree a good chance of Jabo based on both size and pattern. That would put it after 1990. With an Alley (the most likely older candidate for a 1" marble) the swirl pattern would tend to be crisper. It would be easier to see what color was the ribbon and what color was the base. Robwell, what led you to think it would be old? The crease you're showing in the first two photos is called a "cold roll". The marble was just a little bit too cool to for the molten glass to be completely smoothed out on its ride down the rollers.

knob hill!

It's a style which is still being made so it would be really hard to pin down an age.

Yeah, I'll go Alley because of size and pattern.

Oooooh ... pretty

Ooops, I'm behind with my reading. My life just got extra busy as of Friday. Yes, that's a nice swarm of Marble King Bumblebees.

Right about the name slag. The typical manufacturer term for slags was "onyx". "Onyx" became a problematic name in the early 30's if I recall correctly -- because the true mineral onyx industry was trying to get protections against glass makers presenting their products as onyx -- but by then marble makers were mostly switched over to non-slags. Hmmm ... now I start an argument in my head about how Akro continued to use the name "onyx" into its corkscrew-making days well into the 1930's ... but I refuse to delete because most of what I said above is still true ... I think. lol The defendant in the FTC case was Gropper and the order to be very clear about what was meant by "onyx" applied to the Peltier marbles which Gropper was selling. https://books.google.com/books?id=y17ilneaDCAC&pg=PA274

I think odds are pretty good of Champion.

Looks like a lot of swirl for a 5/8" Jabo classic. I'll go with WV swirl of some kind.

Vitro Helmet on the bottom left. Green and yellow looks Peltish to me (upper right quadrant). Several Akro corks, some Pelt Rainbos, other Vitros, a Master brushed patch.

I would assume set. But I gotta leave it to one of the Jabo experts to say whether it all came from a single run and, if so, which run. I'm not recognizing it as the first Joker's but that was a long time ago and I wasn't as interested in Jokers as I was in Tributes.

Ah, and I see someone wrote a date on the bag. Interesting. That fits the marbles.

Yes, Vitros. At least some are Tiger Eyes, in a style which dates to the 1950's.

The brown is a bit weird to me, but much of the marble looks Alley. Size?

Proper Akro Indian Blanket, and a mint Akro Superman, mint Lifesaver. A lot more bumblebees.

Oy. At 1" that's a tough call. Could be a later (estimate 1950's) Master. The colors seem to be in the right general area. The orange peel is making me wonder if it might be European.

Could it be a weathered Master?

another vote for Peltier

I'm gonna guess FT isn't anyone famous.

I'm not sure we're seeing the whole picture. Do these marbles have two patches each?

yes, a pretty cool group

Not a popeye. That's an odd one. If it's machine-made, then I think it got it's twisting from being hung up in the machinery. But I'm not even sure it's machine-made right now. I think it's modern. Size?

With this view and that size, I'm gonna suggest Jabo.

I think maybe a slightly later MK Rainbow on #4. Maybe an Akro on #2. Not seeing MK there.

cool
