The first two are regular Rainbos. Tri-color has gone out of fashion as a name -- I think it was confusing. What was most often called "tri-color" is now called "multicolor". The first two have three colors if you count the base glass, but we didn't usually count the base glass ... we were concentrating on the ribbons. Look for three distinct colors of ribbons. Usually six ribbons in total. And then you have what used to be called tri-color. So, the third marble would have qualified with its red, white and blue ribbons . But as noted, now we call it a Multicolor Rainbo. The fourth is not quite as clear to me. I may be seeing a Multicolor Rainbo color combination -- red, white and aqua. But is it coming from three distinct colors of ribbons? Or is the aqua coming from the base glass?

Small. Then I'll stick with WV swirl. Sometimes when the color is almost all on one side, and sometimes with a hook in the ribbon like you have, we get a Cairo Novelty ID.

Oh, what size? If a big one then maybe Jabo.

I'll say WV swirl, not corkscrew.

30's to 50's does make sense on the date. You have some Peltiers, a lot of West Virginia swirls, one more more Akros.

Some people call the red, white and regular-blue ones Pepsi marbles.

Hi. Welcome. That's a "Contemporary". A modern handmade marble. Sometimes a maker will leave a signature. Do you see any letters or numbers which appear painted on or etched in? Condition needs to be judged in person. From the pictures it looks like this will be NM+ or M. (Near-mint plus or mint.) It takes time to learn to grade marbles. They need close inspection. You need to develop an eye for any little nicks or subsurface reflections ... without getting paranoid about it and blowing some microscopic defect out of proportion. In the meantime if you're trying to sell, then provide nicely detailed photos of all sides of the marble.

Agree with Vitro. I guess it would be in the All-Red family.

Top: I think MK on the ends and Peltier Rainbo in the middle. Bottom: That may be a Vitro Whitie on the left. Could be right about the last two being Alley.

Vitro Cat's Eye. Nice photos.

Alley for sure

Peltier Rainbo. Vintage

Welcome! ... link didn't get there for me. This seems to work: https://www.instagram.com/designsbybing/?hl=af Nice pendant in your avatar over there. That blobby cane look really works.

slush, slush baby ..... to be followed by 9 days with only one chance to break above freezing.

So ... how do we get the orange? Still not understanding. Thanks for your patience.

Looking Ravenswood from here.

Thank you, Royal, for sharing this. Condolences to his family.

Middle and right are Peltier. I'm not getting a handle on the cutlines on the purple one.

Congrats on a popeye in the wild!

Really? That orange is coming from the green? Naturally I considered the possibility that it was from some kind of blend, but I didn't see how we would get that as a blend, so I got my hopes up for Dindo.

That pattern doesn't look modern. But with that vivid green taking up half the marble, I'm not placing it. Maybe Vitro?

The yellow and black is definitely a Marble King Bumblebee. No oddball there. A classic. Alley on bottom right.

Vitro Tiger Eyes It'll start to gel soon!
