Welcome, It looks like you have a nice mix of vintage marbles. In general, marbles with more colors are more desirable than those with fewer colors. Although, some marbles have value even if there are only one or two colors. Size is important too. But condition is probably the most important thing to collectors. Like any other glassware, small chips and scratches can have a very significant impact on the value of a collectible marble. That said, good pictures are key to determining a marble's value. So if you want good advice, you will have to post only a few marbles at a time and show multiple views of each marble. That done, people here will be more than happy to help you, because we love looking at marbles. A few are already capturing my attention and I looking forward to seeing what you have.

It's hard to tell what's marble and what's reflection so it's hard to say.

I do have some crazy Conquerors with that internal structure, so I'm seriously like 50/50. I just don't recall that bright blue on a Conqueror type.

Look close, Tommy. First, the base glass is really different. The "patch" on the Kokomo doesn't thin out in the middle like these, and the Kokomo also only has one ribbon opposite the "patch". I wouldn't expect to find many too many of them. Kokomo made a minuscule number compared to Peltier - probably like 1:1,000,000, maybe not even that.

Both Pelt Rainbos, IMO.

I was going back and forth but the blue and the seam in the last pic looks a bit more Akro to me.

The first one looks most like one a Master "snow globe", but the others don't really look American-made to me.

I have seen one, but I think I gave it to someone - maybe Al.

I think the first and second one are Vitro. The third is Akro.

Put a good light through the second one (not too bright) and see if it has any opalescence.

Nice find.

I'm thinking Alley.

Left one yes, and probably the right one too.

I think the left and middle are Alley, not sure about the right one, but it could be Alley too.

Master made similar called Cloudies. Not sure this is one - lots of cold-rolls/ridges.

I am digging that Vitro with the purple, front and center - where it belongs!

It's an oddball, might be Akro.

I think Master, maybe Akro.

Not Akro, maybe Alley.

Nice Rainbos, some might call the white on black a Skunk.

I think the first is called a Life Saver - like the candy.

Yup.

The first one is a nice Tri-Lite, the black makes it even better.

I'd guess the second and fourth are Ravenswood. Not sure about the others.

Not oxblood, probably an Akro Ace.
