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.

This one is the most interesting to me. I think it might be a harder-to-find American marble from 100 years or so ago. But I do not know for sure that it is, or what the value might be.

That would be a 1940's Vitro Conqueror. Machine-made.

My guess is that this not German or handmade. But that's a whole lot of layers of color for what the glass makes me think of so I could be wrong. (The glass makes me think of modern and Asian ... but I don't remember ever seeing anything else like it.)

Very interesting. More views might help. Maybe a view of the "top".

That big one might be a Peltier Rainbo. Or COULD be a Marble King Rainbow. The thin ribbons make me think Pelt. Only seeing three ribbons so far, in that arrangement brings up the Marble King possibility. I'm thinking vintage though.

Bottom row looks modern. And larger for cat's eyes typically will mean 1970's or later. But four-vane turquoise with a clear base could be from Japan and could be earlier.

Really hard to tell age or maker with clearies. If there is an iridescent finish that helps to ID them as modern. If they're just colored transparent glass, then could be 80 years old or almost new or in between.

The small red, white and orange on the right is a 1960's pattern, but if that's iridescent, then it would be modern. Not sure about the structure on the clear ones. If they turn out to be Vitro cat's caged cat's eyes, they could be a little older. The rest look modern.

Hi. Welcome. It looks like you have a mix of ages, from possibly the 1800's through the 1960's and maybe later. A lot of old ones. Some chinas. Clays. One ceramic which I wonder if it might have been made in America. Slags. Akro corkscrews. Vitro All-Reds. Maybe some Christensen Agate. And some Cat's Eyes. Perhaps post a new thread with a few marbles in it. And a new thread for each new group of a few marbles. That makes it easier to identify which marbles we are discussing.

Those are Vacor Bumblebees. Modern. https://www.billes-en-tete.com/detail.php?id=7

I don't think the black and yellows are the newer MK's. The newer MK's that I have in mine have black around the middle and yellow patches on the end. Pretty sure these are foreign. Probably Vacor.

I think you have an Akro. An Akro Milky Oxblood.

Got it!
