To me, it looks like there might be a mixture from a couple of the JABO Joker runs. And some of them, including the smaller pinkish ones look like JABO Classics to me.

There are JABOs with metal - the "Lawnchair" marbles for instance, and rare marbles from the Peltier Mansion Investor Run actually have silver in them. There are also some Alleys, Champions, Peltiers and others that have real metal in them but their numbers are limited and it seems like more of a fluke (somebody tossed a coin or a beer can into the furnace) than an intentional addition of metal.

That's a good looking marble, Joe - cool base and nice colors.

It looks like an Alley to me and I have seen others that appear to have a metallic sheen in the ribbons - not exactly sure what it is but I don't think it's actually metal, more like chemistry of some sort.

The left one looks a bit like a Vacor to me.

That's a really nice group, Joep - nice find!

There are lots of very distracting/obscuring reflections but I think Alley is a good guess.

I'm on the fence Alley/Champion - atypical whatever it is.

There's not much to go on. The left looks JABO to me and the right looks like it might be too.

I think the Cat's Eyes are foreign. And the big clear blue ones are just machine-made marbles (Clearies/Purees) - industrial, games, crafts, whatever. No real way to tell who made it and it really doesn't matter since they have little collectible value. A bunch of different colored ones can look nice together though.

Well, the orange base color looks about right. I think the green patch is unusual looking. Unfortunately, it's too out of focus for me to say much more.

Nice Alley Flame upper right.

Conquerors are some of the most common older Vitros you will find - Phantom Conquerors a little less so. The difference is between the two is whether or not the body is veneered with white glass over clear transparent (Conqueror) or has internal filaments like yours (Phantom Conqueror).

I think it's really more about the concentration of colorants in the glass and the way those colorants combine to produce different colors. And I do not think MK makes a true black, even today. AFAIK, only Christensen, Peltier, Akro and some old Alleys can show a true black. You can often tell that colors are not true black by looking closely at the edges of the striping where color thins out or mixes with the adjacent glass. But this too depends on the chemistry of the glass and whether or not the adjacent colors of glass are miscible. CAC is famous for using different colors of glass that do not mix together. It's why CACs usually have very nice crisp borders between adjacent colors and very little bleeding.

Alley or Ravenswood, IMO, and I am leaning Alley.

I definitely was not implying the OP marble is Master. I was just pointing you to examples of non-Akro eyelashes.

Nice Vitro Hybrid Cat's Eyes and more collectible than the single color ones, IMO.

I think most are JABO, and I agree the slaggy blue one deserves a better look, although I think it might be newer too - maybe Vacor?

I agree with Steph too.

I agree with RAR too - it looks like a bigger one.

I think Marble King - looks a bit like a blended Blue Boy, IMO.

@Fire1981 Nice mibs, Rick. I have always liked those transparent red ones.

A nice one too!

They're not uncommon on Masters either - check this thread . . .
