MFC's are handgathered marbles. They were made by someone sticking a metal rod into a pot of molten glass, then pulling out a blob of glass, spinning the rod in one direction to get the blob into better shape I guess, and then cutting the marble off the end of the rod. Then the still-molten marble would go down rollers which would help it become more spherical before it cooled off too much. This process creates a recognizable pattern in the glass, typically with a cutline on one end and a "nine-and-tail" on the other end. Your green marbles are machine-made. The first does appear to have a swirl pattern as you mentioned in your original post. The second appears to have a seam, meaning it likely would have come from a company which made patches. That could help narrow down the maker. The maker won't be MFC though.

In the top photo it looked like two yellows next to each other on the top side and two oranges next to each other on the bottom side (with only the white having vanes on opposite sides).

Older Asian. I don't know if old enough to be considered "vintage" (which is pre-1970), but still oldish. I wanted to say Japanese, but I can't swear on that either. With the white vanes being on opposite sides of the marble that's called a "cross-through" cat's eye or "cross-thru" or "x-thru" ... you get the picture. Cross-through cat's eyes are among the more desirable ones. If you can get a non-white cross-through pair or if all three pairs cross through, that's even better. Robust solid color vanes are good for displayability. Translucent vanes could appeal for being less common.

Even with swirls and differences in shade, these are generally considered solid-colored marbles. If small they would be called "game marbles." At nearly an inch, you might have a better chance of nailing down a maker than in the small sizes. But in general, it's really hard to get an ID for a solid-colored marble.

As Popeye the Sailor would say, faskinating.

My thoughts were that distinguishing the ones which actually do look nice and look somewhat like Vitros from the really cheap definitely modern Asian ones with the cold-roll v-cutline could be useful. These pretty ones with longer seams are worth another look. And that extra look could be a step toward finding out who made this style. Names generate interest. And supposedly we're interested in learning more about the marbles which show up more in Europe than in other places. Our understanding of European marbles has a lot of gaps. I see Mojo as ideally positioned to help on the project of filling in those gaps. And I see these pretty non-American non-Mexican marbles as a worthy style to consider along the way of filling in the gaps. And the name "Sherbet" avoids confusion with the names used for American marbles. So I see more pros than cons here.

At minute 17? Maybe the version of Heaton that I might previously have thought was Ravenswood.

We are split into a new thread now. I've linked to the old one, for your reading enjoyment.

Yes, it has a distinct Jabo Classic appearance.

There are some Asian marbles surfacing which highly resemble the Mexican.

21 mm is .83 inches. At that size, yes, the likely options are Jabo or Mexico for modern, Alley for vintage. With the glossiness, modern does seem likely. But I'm not sure which direction to go from there. Possibly leaning Jabo but really not sure.

I hear your assurance that it is clay. I still can't see that though. The high shine doesn't go with clay in my mind. It looks mineral. Normal clays are worth very little even in mint condition.

Typically we will want to see views of seams. You're showing one in this image. Getting clear looks at both seams of a two-seam marble can be helpful in making ID's.

Lighter? Could be normal clay, but it's larger than usual for basic "commie" ... the most common clay marbles. The shininess is also unusual for an older clay marble. But that could mean little to no play wear, I suppose. If it is common clay, then don't wash it. I've had the colors come off when I washed clays.

Yes to Vacor.

A Peltier Rainbo for the general style. A Peltier Muddy for the particular color combination that you have here with that orange translucence inside.

I agree with your reservations -- not a Bennington. Is your sense that it's a lighter or heavier marble? From the pictures I'm leaning toward a newer, more dense clay than a Bennington would have.

Still going with CAC ... or some other old slag ... on the baby blue. The "red" now looks more "amber" ... and it looks vintage. Whatever it is.

Heading out now for an appointment, and I suck at follow-ups, but a note is made. It might happen.

Original Post ... the start of the thread. Or Original Poster in some contexts.

Two seams. One pair of white ribbons. Could be Peltier. I'm not sure but am hopeful for you.

That's a neat bit of history. Disappointing developments but you can display it all together in a Riker case. Still a nice thing to have in your collection.
