It is possible that your beads could be around 160 years old according to this bead timeline. Near the top by year 1850 or so is the earliest these manufactured beads appear.... and, as per The J.F. Sick & Co. Bead Color Catalog, dated 1921 these beads were still being offered for sale.

I have the same beads you showed and their perforations meet somewhere in the midsection too.
