You may want to consult Steph's old list of contemporary marble artists. And hope @Alan will take a look at it too.

There is no getting around the fact that this marble is messy but, FWIW, I think the seam is actually where I've drawn it. The two ribbons on either side of it have come together to produce that blobby mess of a "patch". IMHO, of course.

It's not Vitro. I think a Vacor Dragon is most likely.

Sure enough, there is a bit of UV reactive glass in there, which I don't think is too unusual with these.

Vacor colors, IMO, although I'm not used to seeing that kind of structure for a Vacor, but it is peewee so . . . maybe? If it's American it would almost have to a Marble king but I'm not feeling it.

I was really just wondering if I was missing something that made it obviously Heaton. Heaton did use similar colors and I can see where you're coming from, but here is what I see. I see the seams you see. I see colors JABO used. I also see the "S" sort of structure, the striations in the base, which looks like it has some clear mixed in and is too weak (sort of translucent) for Heaton. I see what appears to be a tight "BC" - it seems to some out of the lower portion of the "S" in the first small pic and extend on into the middle lower pic. And then there is the white washed over the black in the lower left pic. That's why I lean JABO. And you'll never hear me bad-mouth Classics. JABO made some great marbles and this would surely be one of them.

My first thought is a JABO Classic. What makes you think it's not?

FWIW, I don't think it's Vitro. I think it's a Peltier too.

@marblemanvintagemarbles Is the stuff in the center more like a wafer (flat) or a blob? I would expect any pontil to be pretty much on the opposite side of the from that seam or cut-off. Do you see anything there?

I agree with Art.

Yes, it looks like an Alley to me.

I think it looks better, and I've given my opinion of what it is. Might nice to see what @I'llhavethat1 would call.

This one is unusual. I don't see anything that looks much like a pontil. The photos aren't doing much for me. Can you try to describe the marble? Is it green transparent base glass with a big blob of white in it or what?

A few of those also look like Japanese transitionals but It's hard to tell for sure from these photos. It's also hard to keep track of which marble is which.

It's usually helpful to see straight-on photos of any seams, and size can also be important. Can i ask where you are collecting . . . are you in the USA?

I think those are japanes transitional marbles that belong with the very first one you posted.

Like Fire said, definitely collect what you like. I like old stone marbles quite a bit. But beyond agates, they are more of a niche for marble collectors.But there are all sorts of rock hounds and mineralogists who collect modern mineral spheres, most of which, aren't really marbles made for play.

Not quite a "ghost core" but it was heading that direction, IMO.

The right one looks more like a Champion to me. The left is probably Alley.

I think that might better be called a "whip tail".

It's that creased spiderweb looking area - where the marble was cut off the gathering rod. It is probably more accurate to call it a cut-off or shear mark.

I've always been keen on 7/8" marbles - just the right size, IMO. 🙂

I think there is a good chance that this is not an American marble.

If it's American, I would guess Master, but I am not convinced it's American.

It is stone that has been shaped into a marble. Back in the day some were hand faceted (mainly agates), meaning that they were actually ground down by hand on large abrasive wheels. A bit later they were made using water-driven marble mills. These days they are typically machine-made using an orb grinder/polisher - hence, a stone or mineral sphere. Yours looks pretty out-of-round to me - how does it roll? That is the most important thing for a marble. It may have been made by a hobbyist.
