No CAC. It's helpful if you keep the marbles in the same order when you photograph them to make it easier for people who are trying to help you, and take multiple views of each marble showing any seams or other interesting features. All but the orange with yellow one (need more views) look like West Virginia Swirls, which were made by several WV companies and can be a challenge to identify, especially the transparent ones. Most of the opaque WV Swirls you're showing look like Alley Agates, but there may be a Ravenswood in the group.

Opaque one color solid marbles are called "game marbles" and they have little, if any, collectible value since it is usually not possible to determine a maker - all companies made them by the millions, although some can have interesting patterns that might suggest a maker, they still have little to no collectible value. The tansparent ones are called "clearies" or "purees" and similarly have little to no collectible value, although they can be used for decorative purposes. In addition "true black" color was only made by CAC, Peltier, and Akro. The vast majority of "black" marbles are actually dark purple, brown, or green.

Looks foreign to me - maybe a Wales?

I think Alley is likely.

Probably an Alley Swirl

Looks like a roll mark to me.

I'll say, what a group! This one is awesome!

I should have quoted, Rick - I was agreeing with his assessment!

Yup - cool one.

OOgly is a good kind of ugly, Gladys - funky, like Art said. I doubt even Art would call that one pretty!

More Rainbos . . . I like the window into the first one.

Cool pic, Gladys - a surreal sea of blue!

Cool mib, Art, funky it is! I'll go with oogly. 😁

Nice score, Art - it' a looker!

Hey Scott, welcome aboard. There's lots of good stuff here. If you like knives and marbles you'll want to check these out . . .

A few more Rainbos . . .

The colors are looking a bit more Akro to me.

That is what surprised me the most, I was expecting something more like clay. Thanks again for the loose ones, Chris, and the sealed plastic jar full too! I think they're great - so unique!

Thank you all for posting these items! I really enjoy seeing them, since I don't collect them myself.

Peewees are certainly collectible. Other than the yellow Peltier, I think most of the others are probably Akro or Master.

I'm pretty sure the second one in the first pic is Vitro and I think the one with blue probably is too, but the one long seam on that one does cause me a little hesitation.

Nice marble, the first shot looks like a sea serpent or something. There are a few people with extensive knowledge of contemporarys who frequent the board. Hopefully, one of them will chime in but, as Rick said, without a signature mark it might be very difficult to identify.

Some sort of transitional is my guess.

They look like transitionals but might be American Agates?

I'd say Alley but the third might be Ravenswood - it's a little hard to make out the color.
