Hmmm, I want to say Akro but that small blue cap makes me think Vitro.
Regardless of the ID, this one came from the ground--not a pouch, bag or box. It was never for sale as an original imho.
Notice the straitions and the almost ground places as if from grinding against a rock or rubble.
The marbles that I get out of my garden from time to time do not show this type of damage and some come out as "Mint".
I would call it a Dug Patch--maybe even a MK.
Marble--On!!
