Sure is a pretty thing. It doesn't look American made to me. It may be an English Whispler but at over 1 3/4" I sort of doubt it. At that size, Vacor seems like a possibility but I have not seen one like it.

That's a nice variety of cool bags, Al. Thanks for showing them!

A few? That's the only one I have ever seen. lol Nobody has ever dug Master, as far as I know, and that probably at least partially explains the lack of errors you see.

Another one of my favorites 1 1/2" . . .

That's a beautiful red on the last one!

A 15 count Penny King bag with Champion Agate "Whirlwind" marbles in it. Best part, one of the blue on clear marbles is a nice metallic.

Who doesn't like a red slag? I'd like to have that box full!

From our archives . . .

@stonehenge4242 That's an excellent marble!

It's not only a particular red color, it's what Peltier named some of their red slags - Cerise Agates.

Post it in the Sunday Best topic then!

I was thinking it might be from one of the contract run tank washes?

Cerises are pretty hard to find. You should show them off - I'd love to see them!

Like all marble types, there is a range in this type too. I am sure that that good Crows are a lot harder to than find than the same type of marble that doesn't show a good crow pattern. The later were probably dug by the thousands. Maybe the definition of a Crow has expanded to include any marble of the same type, it wouldn't be the first definition that has been expanded for marketing purposes. Having said that, buy what you like and call them what you will. I'll do the same. 🙂

There are a number of good sphere packing calculators on the web that you might find useful. The math is pretty hairy by hand but go for it if that's what floats your boat. 🙂

Yup!

It's not screaming JABO to me, but it could be a Classic that I am not familiar with. You have to be a little careful because JABO is not the only company that produced marbles with this type of structure - they just made a lot more of them than most other companies.

I agree with Akro. They made more slags than any other company by a good margin so the odds are with you.

Bingo! They probably could have called them "penguins" but you know . . . "as strait as a crow flies" and all that. 😄

Not based on what I'm seeing!

If only I had known it was "light pink"! 😄

Here is a nice pic of "Crows" that Steph posted long ago . . . And I think Melissa is right, smaller ones are far less common.

Thanks, Melissa - you're the girl! Pretty marbles too!

@marblemanvintagemarbles When I say "Sometimes marbles "spin" a bit on the rollers", this is the sort of thing I mean . . . New collectors often mistake it for a sign of hand-gathering.

I agree, just an artifact from production - not intentional. Sometimes marbles "spin" a bit on the rollers. In this case, the rollers appear to have had some crud on them, as Alan said.
