Pretty neat. I agree that it was likely clay marbles retailing for $2.00/1000.

Folks are likely paying additional shipping costs too.

Check out the this thread . . . Just page through the thread or search the thread for "Blackies" to find pics of both main types and Anti-Blackies too . . .

Or maybe it is a Blue Colorado?

Interesting . . .

The sorta flip-flop on the ribbons and the big blow-out do look Peltish but I'm just not feeling it.

I think the two on the left are Akro, and the upper right may be too, it looks like a brushed patch error. I'm not feeling Pelt on the lower right, either - they all may be dug Akros, IMO.

I think two Ravenswood on the left, and Alley or Ravenswood on the right.

Marble King called an "Irish", I think.

I agree.

I agree with RAR.

I think it's called a Christmas Tree.

What size is the marble?

It's unusual but I'm getting a Ravenswood vibe.

Probably Alley . . .

Maybe an unusual Alley.

Maybe Champion . . .

Alley and Cairo would be my best guesses but . . .?

It's messy, either way - seems a bit more Vitro to me but . . .?

Might be Champion.

I'm leaning Ravenswood over Alley.

It looks JABO to me too.

Yes, early-mid 1990s JABOs Classics.

I pulled out a few examples to get you started . . . there are more of each type in the mix, and there are other types in there too. 🙂 Vitro Yellow Jackets Vitro Blackies Vitro All Reds (later style) Marble King Patch and Ribbon (earlier style) single color ^^ tri-color ^^ Bumble Bee^^

These types are commonly referred to as transparent swirls. But they do fit the definition of a slag (white striping glass in transparent base glass), and long ago "slag" had an even more generic meaning. I've heard some old-timers use the term "slag" to distinguish glass marbles, regardless of how they look, from stone and clay marbles.
