My first thought was Vitro. I see why Akro is in consideration., I'm on the fence though.

Ooooh. So charming and well-preserved. Very nice.

Your Peltiers are probably from the NLR era, early 1930's. However, they could be from a little later and slide into the Rainbo era. Either way they are a Rainbo style of some sort, not a swirl. Since they have the name of Cross Through, people use that and don't worry about the NLR or Rainbo origin quite as much. Yes, there are marbles which are called cat's eyes with similar patterns but from different makers. But your Pelts predate the cat's eye era which began with cat's eye imports from Japan around 1950 give or take.

Rick, is your marble here blue and white ribbons on a clear base?

I think that marble of mine which was similar and which I wanted to be Alox was ID-ed as Marble King. I never understood the ID. But that's why I'm on the edge of my seat to see what yours turns out to be.

My first thought was Alox. But it's busier than the Alox patches I was able to pull up pictures of.

Is this a new submission? I'll guess Japanese.

You beat me!

I'm leaning Champion on the red one. Again, many would lump it in with "game marbles". I might put it in with them myself in my marble storage. But probably not technically a game marble.

Single color marbles aren't always game marbles. But, yes, one like your right one would often be lumped in with game marbles. If it's bigger than usual game marble size of 9/16", that would be worth noting.

size?

I see one color of ribbons -- blue. To me "flip flop" describes something that happens with two or more ribbon colors.

It does have a fair patch and ribbon pattern. I could see it being a little older than I was first picturing,

Ravenswood had some nice glowy solid-colored marbles ... but the Ravenswoods would be swirls. So if you are seeing a patch-like pattern with two clear seams, then rule my thought out. But if you're seeing a swirl pattern in the marble, then think about Ravenswood.

Ugh, it's hard to say this when people seem so confident. But are we SURE that isn't a modern Marble King?

oh no!

When I see a black banana with a clear base, I think Master. But I gather there are some other possibilities, such as Bogard? I have no idea what aventurine would do to the analysis. Cool mib.

Not Akro. Japanese transitional.

I think it's Bill's turn.

European cat's eye

Hmmm ... the lightened up version looks a bit neon ... so maybe Akro Limeade oxbloods

Jabo oxbloods

Peltier Second Run?

Does look like Jabo. On my screen most of the red looks transparent and thus wouldn't be oxblood. But there are some thin ribbons which could maybe be contenders for oxblood.
