They look like clay. I don't think the fluorescence means much. Maybe something about what chemicals might have been used in the coloring.

I think you're right.

To go with the right two, the left is probably Jabo also. The middle looks like a WV Swirl. I think #2 could turn out to be a Pelt Multicolor Rainbo.

I think Alley Agate.

You are most welcome. I love seeing what marbles come from European countries. Did there use to be more interest? Do you think there are many collections hiding away waiting for people to say, "Oh, I've had these lying around for ages -- I didn't know anyone would like them."

Don't know. Wondering about Cairo Novelty. But I've tried to suppress my Cairo guesses because there can't be as many of those as I used to want there to be.

Poor pups! Looks like it will be a week before we get relief. Our trusty mail carrier today:

At that size and with the iridescent finish, that would be a modern marble, likely made in Mexico. Vacor de Mexico is the main producer of marbles greater than 25 mm. It's very pretty. Someone might be willing to pay a few dollars for it. Larger marbles have their own appeal. It's possible that it's still being made though.

Hello. Welcome to the forum. Those bottom marbles (labeled A) are popular ones. They're called wirepulls. Made by Veiligglas in Amsterdam in the 50's and 60's. The picture labeled B has more common-looking marbles. If those were found here in America, I would say easily American on them. Mostly Marble King, with maybe some Vitro, and maybe a few West Virginia swirls. These companies did export to Europe.

Hi. Welcome. Nothing is jumping out as very valuable. I see a couple of Akro popeyes which can run you $10 or more depending on color combination. The lot could possibly add up to $200 worth if the marbles are mint. Condition is very important for value and it looks like condition could be an issue here. There are a lot of old ones, which could be useful if you're just learning to ID marbles.

I agree on Jabo.

That's great! Go Rams!

I also have a Ravenswood with a somewhat similar brown ribbon but I think the color looks more like my Alley.

I have an Alley with a similar colored brown ribbon.

I see your dilemma. Size? If 5/8, then I'll lean toward WV swirl.

To me this one looks like an Asian cat's eye. Maybe more pix would make me change my mind.

Hi ... yes, I think modern. I think Vacor Octopus. From this century. https://www.billes-en-tete.com/detail.php?id=39

Could have seams. The last picture might be showing "cold rolls" though. Where the glass was just a little bit too cool for the rollers to smooth it out. It might have been made as a "clearie". Lots of companies made clearies which are transparent to be one color but sometimes you can see different colors if you look really close. With swirls inside it might be a Champion Agate.

Cat's eyes may have been introduced in Japan in the late 1940's. (It's possible they were introduced earlier than that by Vacor de Mexico but we're not certain about that history and they don't appear to have had more than local circulation if they even existed.) They (edit: the Japanese ones) became serious competition in the American market in the 1950's. That's when American companies came out with their own versions. Since this is happening pre-1970 those early cat's eyes are considered vintage. The earliest Japanese cat's eyes had clear glass. (Possibly with a slight peach tint, I have found.) Nice glass. And American cat's eyes had nice clear base glass. The Asian cat's eye glass started getting cheaper and they took on a bottle green or gray tint as time went on. Then in this century, Vacor came out with crystal clear bases for their cat's eyes ... very pleasant to look at ... but that complicates the dating process.

lol ... now I"m trying to find a picture of a weather vane with blades ... and I'm not having much luck ... so ignore that part! lol But they're "vanes".

Those are "vanes". Like the blades on a weather vane. The earliest cats eyes had wider vanes making it more obvious why the name was chosen.

Pretty sure modern on this one. Maybe a Vacor Orca: https://www.billes-en-tete.com/detail.php?id=43

I think you have a Master. Maybe 1940's or 1950's.

Left: Vitro Conqueror. 1940's. Right Vitro Tri-Lite. 1930's. Middle: not sure. From here is is showing modern Jabo properties. More views could help.

I think modern. Not sure but I'm getting a Jabo feel from these.
