I don't know who made the first one, it could be foreign. Looks like blue AV? Master made some I believe, but not the swirly types. MK made some with heavy AV too I think. The swirl ones are still debated but mostly attributed to Champion, although that would be about the only marble they ever made with intentional AV if so, which is odd. Plus many were big for Champion. The solid black AV non-swirls could possibly be from Pelt.

They are only unopened once. They don't make them anymore. I've seen people open bags of tiger eyes and rainbos just to see the new common shiny marbles. Those marbles that are worth 50 cents each if you can find someone willing to pay that. But the still-sealed bags have the value. They keep on getting opened and one day there will be so few left that the value will be up there even for the more common stuff.

..........no words right now. Been on the phone and this is still such a shock. From doing yard work to gone in minutes. Cherish every breath folks.

Later St. Mary's Alley if you ask me.

And some people keep trying to force a square peg into a round hole.... I'm amazed how often someone tries to force their marble to be something it isn't and they get mad when they don't get agreement.

Same stuff I see in the OP and why I lean CAC.

The spidery wrinkled cut mark and milky weak colors.

Pattern screams CAC to me. Straight cut, tapered tips, the way it swirls... if this was another color I wouldn't hesitate to say CAC and move on to the next without pause.

X 2 Master.

Torn between CAC and Peltier here. Leaning CAC mostly with the little holes in the white, the size, and the squiggly zig zag in the pattern but could be wrong.

Japanese transitional here too.

Messed up St. Mary's Alley here.

Found some pics online

Bert. Not Brian. Bert Cohen. He had them.

Yes, the Romans made some glass marbles. There was a collector, I forgot his name. Someone help... Brian something? Last name maybe started with E? I'm so bad with names. He had a collection of them. Let me do some looking.

I'd be wanting to lean Sistersville Alley on all of them in this thread.

All Alleys. I like the top left type with mottling. It's from St. Mary's. Top right is Sistersville. Bottom Left St. Mary's, and bottom Right may be Pennsboro. Alley factory trifecta!

Yep that would be me

Keep em with Cairo. Good ID!

Here are some more, many different and unusual ones. The first two are big 1" and the dark green and black and grey with white mottling is also a shooter.

Four pages on the topic here and how to separate them from one another: https://www.allaboutmarbles.com/viewtopic.php?f=5&t=44918 FWIW I'm the guy in that video showing how to tell them apart.
