You have a rather nice collection of beads. I see some Hudson Bay beads ( red with white centers, tubular shape), a nice assortment of Seed beads, and some Pony beads (ones just larger than the seed beads).
Hey rock... They call them trade beads because they were used as trade by Europeans that should give you some indication of the timeframe.
Great collection you have there I could see myself sifting through your property.
Metal detecting too
