Those are some nice marbles from the 1940's to 1960's. Maybe some from 1930's.
I don't see pricey ones.
It's a solidly vintage group though. That's a good sign. And someone might recognize more value in some of the swirls than I do.
There's a red, green and white one near the top I'd like to see the other side of.
(That's what I wrote in response to post #4 before I saw the notice for post #5.)
In Post #5, at least two of those look like Vitro cat's eyes. Maybe all three. Cat's eyes are generally among the less valuable marbles, but you have a three color hybrid there and that raised the value of the cat eye. I'm not sure how much to. But treat that one nicely.
