Vintage Antique Three Glass Crumb Beads Loose Green Yellow Blue Speckled Trade ?

Description

You'll receive all three!  I'm not too familiar with beads but my research indicates that these three are handmade glass 'crumb beads.'  Possibly trade beads?  Two of them are short bicones ? and the third is a rounded one.  One bicone is mostly yellow/greenish speckles with some red on black.  The other bicone is actually a very dark blue with mostly red and white speckles.  The rounded bead is multi-colored speckles on black.  The two bicones have rough or chipped edges at the center hole.  All three have minor imperfections from the creation process.  Please see the photos for sizes and details.  Thank you!
