They sure look like MKs to me.

I'm with Melissa - they don't look like Cosmic Rainbows or Painted Turtles to me, but I wouldn't rule out MK without a few more photos. It's obvious they are all the same though, so detail photos of one or two of them would probably work.

@marblemanvintagemarbles Be sure to check for AV in the green. It shows up in those occasionally and this one looks like a good candidate.

@Tommy It does look better with the bag, for sure. Myself, I think it may have been some kids favorite cricket box - probably took it fishing. lol

You said it was Kokomo earlier, and I agree.

I think it's an Akro slag too - just way more than its fair share of white.

@marblemanvintagemarbles Ha, at first glance I thought it might be a Vitro yellow jacket but then I realized it's only a two color marble - a common Alley (second marble too). What's up with the red halo around the edges of your photos - you're throwing me off kilter. lol

That's a Type IV Tiger Eye.

Nice clean ones @davesnothere. Another recent find . . . 11/16" Tri-stage Solid Core.

I'm seeing JABO.

It's a helmet variant.

I'm seeing a Lazy Akro Corkscrew.

You know, some people might say I have a clinical issue, but there are some game marbles that really float my boat. Master Cloudies, for instance . . . notice the seams - just like other Master Made Marbles. And Vitro Tomatoes . . . Seams and pattern just like lots of other Vitros. See the "V"?

Mwah!

Some early ones definitely came close: I think these were from a 2009 wash out.

Still my favorite day of the week . . .

I wouldn't say the marble on the left is a game marble - some kind of WV Swirl, but I'd need another view or two to attempt an ID. The one on the right looks more like a game marble to me. One interesting thing you'll find if you study game marbles enough is that even though they are one color, they still often have the traits that are typical for the company that made them. In other words, seams (or lack of them) and patterns are usually similar to the company's other marbles.

@Fire1981 started a great thread here. Let's keep it going. Here's one from Greg Pessman . . .

Asian would be my guess.

I agree with common Alleys.

I agree with both of the above.

I agree that they are newer MKs.

I'd recognize Ron's handwriting anywhere.

You're right, I can see it's tough to photograph - my first impression is JABO.
