Wow, that's some deep digging.
Some of the key things I picked out, was "seventy-five cents to a dollar" , per marble, was a substantial nugget of coin back in that era.
The last round of pics look like a few Vitro's (Pelt on the first one). I see at least an Alley (blue/yellow) and a couple Marble Kings in the original post.
Good eye Steph, I was distracted by the top two on the right. And then got to thinking about whether or not the green one's might have Aventurine.
Nice marbles, they look good together.
Most of the big one's I've come across aren't in the best condition, so yes they got played with at some point...(or maybe fell of the mantle)
They were the one's I aimed for in my playground days. lol
Hard to tell as both CAC and Alley made marbles with those colors. Looks like it could be an Alley. But...(what looks like a cutline) and the '9' or "turkey head" pattern makes you think twice. Any still photos? What's the size?
They all stand out (as German swirls). Bottom right is an alternating white/yellow core latticinio. Hard to tell from the other pics of what you have there, but there are a couple worth another look.
view 3.jpg looks like a green Jelly core. Probably not intentional but that's what I'm seeing. The green was probably intended to be on one of the white outer stripes but you can imagine the patterns can get wonky
Based on the one pic I'd guess it could be a bubbly Akro but more angles would help. What's the larger handmade on the left side? Some clean looking marbles.
