The white one with the black speckles is one of the newer ones. Likely Vacor.

Looks like Akro. If a slag doesn't have a clear pattern such as Peltier feathering or a Christensen seam, then chances are it's Akro.

Transparent swirls can be especially hard. I mostly group my transparent swirls together.

Subscribed!

A mixture. 1950's (or maybe earlier) through 2000's. Nothing very valuable. To me the most interesting is the large swirl in your last photo. That's one of those Veiligglas wirepulls from Amsterdam. It appears to be damaged though. You also have a smaller Veiligglas up there, on the bottom left in the first photo.

Hello. Welcome! I find computer generated races fascinating. You programmed it?

I'm getting a bit of a Vitro feeling from the top right in the first photo. (Bottom left in 2nd). More pictures might help.

Wondering about Cairo Novelty on the red and white.

The pattern on the one with black around the center and white on either ends could point to a modern Marble King or a sort of plain Vitro Blackie. (We usually think of Blackies as having a white base with a black ribbon around the middle and colored patches on the end). But the glass texture isn't matching either one of those for me. Maybe other lighting would make me see it differently.

thanks ... The bottom right one of the first photo (top left of 2nd photo) is a Vitro Tiger Eye. From the 1950's. I thought maybe Alley on top left in picture 1 (bottom right in picture 2) but with the color pretty much on one side of the marble, that's a possible sign of Cairo Novelty instead. Middle right of picture 1 (middle left of picture 2) could be a Master or an Akro.

... as to what caused the circle ... I don't know. If it's not a chip, then the marble might have gotten caught on something and then when it got free that's as round as the machines helped it get.

It's a nice vintage group. My brain is sorta mushy right now. Can't take on a big picture ID at the moment. Someone else might feel up to it. On the bottom row, second from left, I think that's a Peltier Peerless Patch.

Top marble ... not sure ... maybe a slag or an Akro corkscrew or ??? ... more views would be needed for an ID ... but it has several dings, so it probably doesn't have much monetary value. Next marble looks like a West Virginia Swirl. Sort of a generic marble. Third is a Vitro All Red -- a very common marble. The last looks like maybe a slag, also I think with damage. As I said in one of the other posts, I think $75 is probably a fair offer. It's possible though that someone else will look your marbles over and see something they would consider a steal at that price, so wait for a second opinion.

My first impression is that $75 for the lot is probably a reasonable price. But wait for a second opinion.

The biggest one here is a cat's eye ... cat's eyes aren't usually valuable, but someone might pay just for the size. Another big one above the biggest one might also be a cat's eye. The big marbles on the left are slags, which are popular marbles from the first three decades of the 1900's. The black and yellow marbles might be Christensen Agates. Christensen Agates are a popular marble but two color ones without special patterns still probably wouldn't bring a lot of money. You also have some Akro Corkscrews here ... with a lot of damage. Even one small ding can lower a marble by more than half of what it would be worth if completely damage-free. Soooo ... that's part of what you have in this group.

The two big ones more to the middle (with red patches) are 1960's Vitro All-Reds.

These are older -- like 100 years old or more. Not very valuable though if all of them are some kind of ceramic or earthenware like I think I see.

Looks like you might have an interested blue and white (and clear) swirl in with your cat's eyes.

Some of these look like "fried marbles" ... a fad from the 1960's where the marbles were subjected to extreme heat and/or extreme cold to get a crackled effect.

There's some chance that some Akro moonies or flinties are in with your game marbles. Those would be an example of a more valuable solid-colored marble.

Clearies were popular in the 1960's -- helped save Vitro's business. I like them. But neither game marbles nor clearies are usually considered valuable.

The solid colored marbles are called game marbles. The smaller ones especially. For their use in such games as Chinese Checkers.

These may be some kind of industrial marble:

There's much wear on the glass. Maybe from being played with. Being stored with steelies takes an additional toll though, so separate your metal from your glass.

These are common clays. The kids sometimes called them "commies" ... for being common.
