I'm loving learning more about marbles being here! The seams post pinned has been really helpful as I'm starting to learn, though I can tell I have a long way to go.
I have a handful of marbles that were given to be by a friend who told me they were old, but I'm not sure how old. If anyone wants more photos for any of them, let me know, but I'm mostly asking about this small one that looks rather odd. It's really different from anything I've seen before and I don't think it's glass.
This might be a dumb question, but does anyone know if it's even a marble? Thank you in advance for any help anyone can provide!
