Venetian Lamp-Work Mid 19th Century Trade Beads

I sent pictures to the Illinois State Museum asking if they could give me any information about these beads. Illinois State Museum has an extensive collection of Stephen Fosters Merchants Trade Beads that the Foster Company imported during the 1800's.
I received an answere from Jonathan Reyman Phd. Curator of Anthropology and Collections for the Illinois State Museum.
He said the Beads all of them are Mid 19th Century Venetian Lamp-Work Trade Beads.
I'm trying to find a value for the Beads.
