Vacor I agree, that would be my guess, i have an album in the gallery with most of the known Vacor - Mega marbles Sherry, if you want to take a gander.

Akro IMO, the fracture does hurt the value considerably, yes !!

Biggest Sulphide, just a hair over 2 1/2"

Alley here

Good luck my Friend, 9/16ths are good to hold onto also, small corks are VVVHTF

Looks like it to me, nice and clean, man if you ever get a pee-wee cork hang on to it, I've only seen one in hand in 35 years.

X3, Vitro, Vitro veneered a lot of their marbles like this one was

Asian IMO

Two Antique handmade Germans W mica

"Welcome Melissa"

not seeing mica !!! the green base glass is the reason for the high price

This may help, I'm a little lacking on the subject, never collected either. Make sure ya read the whole post, I had to to grasp what they where talking about. Good luck Brother, hopefully ya run into a collector of such. LINK :: https://www.allaboutmarbles.com/viewtopic.php?t=52483

Any Sulphide in glass other than transparent clear is going to fetch a good price, the same with any figures that are painted, even if the glass is transparent clear. There are also some rare figures, mostly busts of humans and a double or 2. Most of the double's are fakes though, you better know what you're looking at. The so called (California Sulphide's) had a lot of doubles that fooled a lot of collectors for a long time. Do a little googling you'll find them.

?????????? not enough for me, wish i could help more, Master would be my best and is probably wrong !!

Vitro IMO

It's foreign, probably Vacor IMO

X3, Vacor

Caged solid core IMO, i can't see any separation in the wide and thin ribbons in the cores, if there is it's a tri level.

correct, this one is 100% CAC, no fading and good CAC structure, they're getting better and better at imitating, it's getting verry hard to tell. No color fading here, nice marble !!

I see a lot of color fading which doesn't happen when you use batch glass.

X3, Japanese cats to me also
