An American Agate type, maybe?

I would say those are both Vitro - patch and ribbon style. The right one is a nicer marble.

The base might have a little opalescence but it is not an uncommon trait for the base of translucent Rainbos to look almost transparent with strong back-lighting. Because of the way light reacts inside of glass, a little bit of color in the marble can make the whole base look colored. As for the brown striping, it is a bit less common on Rainbos.

Welcome! You have a variety of vintage marbles - some appear to be foreign (non-USA) made and most appear to be in pretty rough condition, which signficantly limits their value to collectors. The big red and green one is an Akro Corkscrew, which would be a desirable marble if it were in better condition. The larger tan one with green stripes is a Peltier Muddy, which in better condition, is also collectible. I would be interested to know if you see sparkles in the big green one with white stripes. It might be an Alley Green Giant, which would show a lot of aventurine sparkling inside in sunlight or under a bright light. I also see a few Vitro marbles, including cat's eyes, some West Virginia Swirls and a some foregn marbles, mostly cat's eyes. I hope this helps!

I am sorry to hear this. My condolences to his family and friends.

I'd say Pelt on the left and Akro on the right.

It sure does, Ron. At first I thought it looked a bit like a Jackson but the blue is a bit different than the similar Jacksons I have. And I thought Cairo used some of that dirty Vitrolite too. They did make marbles that fluoresced, right?

I appreciate the offer, Bruce, but I'll keep it for comparison purposes, so I don't fall for another one.

Thanks for helping me think about it, Steph. It gives me the feeling of a late NLR or early Rainbo, so I think "tweener" is probably a good call.

I agree the buttery one on the right is pretty cool looking. It looks like it might fluoresce. Have you put it under a blacklight? Lot's of transparent swirls are pretty in a simple way, and it's easy to get lost looking at them. I have a few gallons of nicer ones I've collected over the years and it's a lot of fun to go through them every once in a while.

At that moment, Steph, I was thinking more like a hammer. 🙂

It's mint or very close, Bruce. I am just not a big fan of CAC and I was hoping it might be Alley.

Akro and Master made the majority of brushed patches you'll see. In my experience, Masters usually have a pretty "pointy" (or tighter U) type seam on one pole than Akros and they may have more going on inside of the marble. In addition, you can often feel the seam on Masters with your fingernail, which is a less common on Akros. The ones you are showing here look like Master Marbles to me.

This is a good looking group, Bill. A lot of Akro's patches are underrated IMO.

That's what I was thinking too, but what in the world would you call it? One side looks more like a MCS and the other looks like more like a Rainbo. NLR?

Rats, I didn't think CACs bled and thinned out like that. I may have to see what it looks like on the inside.

Maybe a bit of bifurcation?

The colors sort of bleed to brown and thin out in spots, which seems a little odd for CAC, and I have seen that "fireplace flame" coming out of a pouty seam on quite a few Alleys, and the inverse flames coming together on the backside too - I can only hope, I guess. 🙂

It's been unsettled for quite a while.

A little early but . . .

Metallic Bruiser:

What do you think?

Just a couple of purty patches: I just can't pass up that raspberry color on a Vitro.

These are the Cairos from Everett Grist's Big Book of Marbles (3rd ed., 2006) Plate #209, p. 97.

Some of that dirty Vitrolite in a Jackson:
