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.

I agree with Fire, Peltier Rainbos, and not too unusual, IMO. I don't think they don't think they right for Kokomo.

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.

Sure enough, JABO Lawnchairs. There were a couple of different runs. I think these came from the first of them. I think @Melissa has some prettier ones from a later run.

Yes, what might usually be red is orange. It's a good Akro, for sure - harder to find than a Superman, IMO. I'd be interested to hear what @disco005 might say about this one.

You know, Vitros are about the only marbles with seams I have ever given one whit about but that has changed since getting to know the El Aguilas better. It's sort of odd, but I think I'm getting a little bored with American machine made marbles.

@akroorka Don't forget El Aguila, which I think this is - the colors and construction are spot on. 😁

@Parmcat Really man, go easy on yourself! 😉

When I think of Vitro oxblood I think of this . . . And maybe this . . . @VaMarbles If that one was mine, I'd have it with my Akros.

I thought I saw a hint of it in your pics. 👍

Late 1850s into the early 1900s, I think. You might also see them referred to as variegated stoneware.

Sort of a fancy clay swirl - It's called a Jasper or a lined crockery (German). You can find them with green, blue and/or pink lines.

This shows the sort of cage-like structure that you're looking for in the core of a latticino.

I had a reverse brain glitch - it's a JABO Ace.
