Well you guys must have better eyes than me if you can determine "polished" from these pics.
What I can tell you, having handled a bunch of Greiners in hand, the glass is prone to seediness and blowouts
Even more so on examples with oxblood. Probably related to formulation and primitive techniques being used at the time...keeping in mind this was at the forefront of glass marble production.
Just my 2 cents worth. I don't typically comment on open auctions.
