Some math to go with that suggestion: If an 11/16" marble were a triple ingot, it would be made up of three peewees. (7.6/16" each) If it were a double ingot, it would be made up of two marbles under 9/16". (8.7/16" each) Just for reference.

Lotsa logos and some Jabos.

I went to the Wayback Machine. There seemed to be a lot of snapshots from 2006, so I picked one of those. Check it out. Innerchild's Memories -Marbles and Toys -- Home Innerchild's Memories - Marbles and Toys (archive.org)

I'm not seeing "Zebra". I'm getting a Rainbo feel. Amazing Rainbo of course.

Interrreesssstttttiiiinnngggg. Double checks? Like checks for value? Check for chips?

Good luck! 55 plus Vintage Marbles Pelts, Arkos etc... Plus 28 damaged. | eBay When you ship them, remember to pack them in a way where they are cushioned and won't rattle around and hit each other during their travels. So that they arrive to their destination in the same condition that they started out in.

Not because of a buttcrack, but because of the multicolor striations, my first thought was also Jabo.

I don't think that is American.

First, take that steelie out of the group. Marble collectors cringe to see the metal near the glass. Next, if you can sort out the ones that don't have nicks or wear, you might want to sell those separately from those that have more wear. Learning to grade the condition of marbles and to identify them by maker are both skills which take a long time. But if you can at least learn to grade condition enough to separate out any mint or nearly mint ones, you might be able to get bigger dollars on those. And then whatever you got on the leftovers could be bonus. Just a thought. Selling marbles can be an inconsistent game. Especially if it's not someone's specialty.

That last one was well-loved! A nice start of a collection.

Clean gently. Too hot or too cold water can crack them.

Nice vintage group! Good find. Not that easy to get seriously vintage marbles at estate sales.

Okay, then my guess is wonky Vitro Opal.

Being a "single seam" makes it an oddball and could make ID-ing harder since it doesn't fit the standard pattern for the most likely manufacturers.

Is the base opalescent?

Not a parrot. Pictures in other lighting, on a less textured background might help us have more ideas.

Pretty sure that's a Marble King.

Quick picture snag from an ebay auction for "Marble King Beach Balls".

Marble King on the right. Am fairly sure about that. I'll accept Pelt on the left, though I wasn't sure at first. Something about the glass texture. Probably just a trick of the light.

My first thought was that the colors looked like modern Marble King but I didn't think it would be MK because the white is an equatorial ribbon instead of end patches. At this point I don't know if it's modern or vintage. If it's vintage, I'll leave it to you guys to sort it out. If it's modern ... could be Vacor.

Wiggly, irregular vanes could point to Vacor.

The supply of 1930's marbles is dwindling. Cat's eyes are more accessible ... and more familiar to people, nostalgically speaking. And there are forums dedicated to them, which has to raise interest. Maybe this is a flash in the pan and sellers need to dump while the getting is good. But maybe their time is come. In 50 years, the "vintage marbles" will be the Vacors being rolled out now.
