In Ravenswood, look for a more organized ribbon. A stream you can follow that swirls in a more graceful manner. Not that Heaton can't do the same, but many Heatons have this short stream construction and RWs have a longer stream making up the marble in general.

Nice! Those are St. Marys Alleys. Looks like they are the contents of a box or bag and have stayed together through the years. The one looks like a fancy or exotic type or coral I think. Would be a great group to keep together and not mixed up with others to use as fill for a box or just for posterity.

Heaton. Nice pics!

Purple slag. The pink is an effect of the white under the purple glass.

Pelt.

He says, "Auf, auf, und davon!" I know... groan. (that is German for "up, up, and away!)

About half of corks spin one way, half the other. Not sure how the direction one spins can be a trait. Pelts can spin either way too or not at all. How do you explain the ram's heads then, which swirl both ways?

Mine all have 2 seams like a start/finish of the stream. They look just like the OP photos but different color.

I find these in bags at thrift stores. They are intentionally made like this (sort of a pyramid/gum drop shape), not intended to be a marble. They are for flower vases and decoration. Modern.

Champion.

It likely is Ravenswood IMO but not a blue raven for sure.

Ravenswood here.

Yes on Heaton B/Gs. We used to put them with the Champions because like Ric says, Champ made them too and we didn't know Heaton did until recent years. The champ ones have a whiter base and a busier "wad of chewed gum" pattern generally. Here's a champ single pic and a Heaton collage pic.

Alley. I agree the pics are funny but I recognize the type.

That's not a Vacor.

The clear and purple WV swirl is a Champion.

Vacor

It's Asian all day. If you haven't seen any like it yet in your very short time dealing with marbles, that doesn't make it so. I've collected since the 1980s and still see things I haven't seen before. I have a jar of these I keep around and put the rest in tubs full of marbles to give kids at marble shows. On facebook groups you'll find people who will agree with anything.

No clue on size but it looks pretty huge sitting on that nut. So probably Akro.

Seems plausible to me.

No, Cairo.

Blue devils are around 7/8" and have a cobalt blue base with white and purple. Can be somewhat of a swirl or a patch. The swirl type seems to be more common. There may be some rarer examples in smaller sizes and sometimes the white doesn't show much.

Two Alleys. Lots of fractures in the first unfortunately.

St. Marys to me.

Champ. These were some of the last marbles run there, found in 55 gallon drums at the auction of the factory contents.
