It is an interesting mix of beads.
The small blue ones look like recycled glass beads from Krobo, Ghana. They are probably not very old.
The other bigger beads look like a mix between Venetian glass trade beads, probably made between 1880 and 1930 and powderglass beads, again from Ghana. The ones with a rough surface are the powder glass beads. I am not very good at dating powder glass beads, but I think these are no older than 20 or thirty years.
Other who can add/correct?
