That would be my best guess as well.
Not a "Moonie"--- Moonies present as white in hand--all types-- or all two types, Akro and CAC.
Master Marbles of all sorts will present---more often than not--Master cutlines.
Marble--On!!!
The two on the left are WVS imho.
The one on the right is a Vitro Aquamarine. Good eye!
Nice marbles!!
More opinions are needed and welcomed.
Marble On!!
I learned this much from @wvrons.
If they are 9/16", they are more able to be considered as Ravenswood marbles.
The sizes always matter. (even if I skip reading it sometimes-š)
Marble--On!!
Here is a list of sizes from a "Salesmans Case".
The peewee size is not even listed. 9/16" marbles are hard enough to find imho. That being said; there might just be a few peewee corks floating around out there in marble land. I have never seen one or heard of one though.
Marble--On!!
I was thinking maybe a Champion from the start--a pretty big one though?
This is a nice looker with some nice images as well.
More opinions are needed and welcomed.
Marble--On!!
