I'll go with Master.

I want it to be Vitro. With those colors, I wanted it to be Peltier at first, but since the ribbons aren't in pairs, I am moving to a Vitro suggestion.

Yes, in general, cat's eyes are not popular. Cat's eyes often subtract from the value of a mixed lot. I would have bet on you being able to sell a lot full of super-sized marbles, but yeah, basic six-vane cats with that orientation of the color are considered very common.

Hmmm ... maybe more pictures from other angles would help. But some remain a mystery.

Love the display!

I'm feeling good about the Amber being Pelt. I felt pretty good about the blue and white being a Vitro Cat's Eye. Because the vanes weren't very wide, I wondered about Peltier, but I think Vitro is right.

Sushi love

Here is the start of my long-promised replacement of the seam tutorial I accidentally deleted a couple of years ago. Some companies are known for more swirly marbles. Some are known for having lines or patches of colors which run from seam to seam or pole to pole. If marbles have poles or seams it is helpful to show them when looking for IDs. Rather than try to define the jargon I'll start by posting examples. And rather than wait until I have all the photos ready, I'll post them as I take them. So here I am starting with some Master-made marbles. Masters often have relatively small U-shaped or V-shaped seams or "cutlines". Some people might consider them to have "poles" where the ribbons come together on top and bottom. I took photos of both poles here. Sometimes seeing both ends can help with the ID.

If it's a Peltier you should be able to identify two seams, where the ribbons are going to the seams. I promised to have a seam tutorial ready this past week ... but it didn't happen. Working on it right now. Identifying the seams goes a long way to helping us see the structure. Very important for id-ing when we don't have the marble in hand. Well, I'm going to start posing my marbles now to take pictures of their seams. Will be back when I get it done.

Thank you kindly, sir.

12. Not seeing the structure well -- it might turn out to be a Peltier Rainbo 6. Pretty sure Master 2. WV swirl 4. Probably a Peltier 8. slag 10. I think another slag

4. slag 6. Master 12. slag 10 is the awkward kind where the tired brain thinks transparent WV swirl, but then thinks slag, but then things WV swirl, but then ..... um, I think it's a transparent swirl 8. transparent swirl 2. Not sure if it's a WV swirl or modern

I like the dark strands also. Probably errors. On the last one ... are you seeing what you consider a cat's eye structure there? The ribbons running in straight lines from end to end? If so, then might be a Master.

The 1"-ers are worth a little more for being one inch. I'm not aware of demand for Vacor cats. But that doesn't mean it doesn't exist.

Left Peltier Right ... I'm not getting a good idea of the structure. Is there just one strip of white? A sort of disk?

What size is that?! At that size, for a random out in the wild marble, Vacor is the most logical choice. The only other thing I could think of would be a Jabo double ingot, but I don't think anyone would let a Jabo double ingot of that size out of their house!

No ... almost a clearie ... not seeing definition ... Champion?

Since the swirl ribbons are sort of fuzzy, I would think Champion over Alley.

The dark ones are machine-made. I think modern and foreign.

Vintage is generally considered pre-1970 The NLR is from around 1930. The MK Rainbo is from around 1960. WV swirls are generally vintage -- most WV swirl companies went out of business by some time in the 1950's. Champion lived into the modern era so can blur things a little. Alleys are from around 1930 to almost 1950.

Yeah ... Akro cork

a special one

Yes!

With the frilly vanes and the clear base, this could be a Vacor.
