duotone

I agree—beauties. I think the question is: are these Supermen? Does a Superman need opaque red rather than this transparent red?  I'm wondering too...

I agree with Fire, center one looks Ravenswood and right looks Alley. No idea about the one on the left. 

Yes, haven't seen one with these colors but it could be a Vitro Victory.

A very nice example.

I agree with Veiligglas opaque swirl. Some of them look like Alley calligraphies. 

Agree with CAC. I've seen this listing—nice, and the size is appealing. 

Both Peltier Rainbos. 

All Marble King Bumblebees. Veneered yellow and black, with much variation in how those colors are applied.

Could be a Vitro Opal.

I'd say it's a Vitro Bulls Eye.

Looks like a twisted up Peltier Rainbo.

Agree with Master. Good colors. 

I agree with Alley. Noteworthy that it has that fingernail element that Ron Shepherd pointed out in Alley identification videos. I see it in the 5th and 8th photos. 

I agree with Vacor, possibly a Zombie. From this useful identification site: https://www.billes-en-tete.com/detail.php?id=134

If you haven't seen it there's an interesting post from Cheese over at AAM about identifying marbles based on size. Following that guide this marble could be either Alley or Jabo.

I agree with most here that these look CAC. The patterns and separation of colors lean toward CAC to me. 

Agreed, looks like an Akro Snake. Nice.

Agree that it's a WVS not a slag. Not sure of the maker though. Maybe others will chime in.

Agree that it's a natural stone sphere, not a marble. Looks like Tiger's Eye.

I agree with Marble King—later, I think. I've seen these called Anemic Bees. 

Yes, looks like a Vacor Spaghetti.

Agreed, Peltier Rainbo, satisfying colors. 

All beauties. Double ingots resulted in great patterns here.

I agree with Alley.

I agree with Fire that the ribbon on the outside is black. Good to know about how the light blue streak inside affects classification, though.
