That is a nice mixture of 30s-50s machine made marbles, There are Akro, Vitro, Marble king, Peltier, Alley and other WV company swirls in there I see at least 8 Akro corks, I will post some examples later so you can pic them out. The last marble on the 4th row looks kinda neat Probably a Vitro Agate. Jay
