No, they are greener and similar to that one but not with a ground pontil. They have what I would guess to be pinched or folded pontils. I've only really just began any kind of serious pursuit in the understanding of marble collector ins and outs.
As to what I stated about the marbles being single pontils, I was wrong. Upon closer and broader examination i have found that they're not quite perpendicular with one another from end to end so as to meet up if you were to draw a line; but there are two on most which line up more with what I would compare to a ten minutes to six position, if you were to refer by comparison to a clock. There are some that are single pontil which I would assume are the end of the cane ones.
The glass appears the same aquamarine that become of many jars, bottles, and other glass goods from the mid to late nineteenth century and early twentieth century.
If they are old wouldn't that alone make them collectible?
they've got bubbles, they are not consistently the same size, and they are not all perfectly round either. Don't those qualities indicate an early production timeline sometime between being handmade or transitionals?
