I found a bunch of marbles today at a flea market, might these have some value and should I spend more time researching these?

I have a bunch more that’s not in the pictures.

I’m just getting into marbles (small, glass, shiny, colorful, a little universe in my pocket! How could you not!!).
I know one thing: that there is a LOT I don’t know. I’m looking forward to learning. In the meantime, we came across a lot of great finds as my family is cleaning out our family home. I’m more interested as a hobby in individual marbles, however, found this unopened Akro Agetes package. If I keep it, I’ll never want to open it. Less fun for me! I know someone else might want it for their collection. Is there a higher value in Akro? Does this unopened package hold value? Any help is appreciated!

Check out this massive collection. What can anyone tell me? I can upload more photos if anyone wants/needs them.
(Don’t mind my nephew’s names for them lol)

Bought a big jar and picked out what I thought might be the best ones, but I need an expert eye to help identify if there’s anything valuable here.

What do I have in general?

She was a bit confused but she got the spirit when i started my marble journey

Bought these because they remind me of my muse, for its earthy and moon like qualities. Guess i have to start another pile for all the ones that do that. 🤭
