This was a $10 batch of marbles I got on a local second-hand site. I think I did ok! So I know these are old German marbles, and though I don't know the exact taxonomy for them all (caged, divided core, etc???) I can recognize that two of them are onionskins...but what is this green thing?? it has a few flecks of mica in there. What do you call it?

So I got this pretzel jar of marbles off Facebook marketplace, and confirmed with the seller he just got it from an estate sale. Whoever owned it previously was clearly a collector. $60 later I’m finding multiple modern art marbles, 6vitro conquerors, some vitro’s, some akros, and quite a few I can’t pin down but know are vintage visually from pop quizzes and whatnot. Am the happiest boy, and will be posting and asking questions on the ones I don’t know in the coming days. Even though I know the bottom half of the jar is all cats eyes, I’m still excited only being a 1/4 of the way through the jar >.< pretty sure this is my best random gamble/purchase so far

Are these Vitro wedding cake marbles?

Very new to this, picked this board and marbles up from an op shop today. I think some of the marbles may be vintage but some may have been replaced with more modern ones?
Just after some thoughts please :)

Thank you!

this beauty came as one of several surprises with my ebay purchase of a vitro tiger eye.

any ideas?
