That's a 100 pack of Anschutz pellets (probably made by another manufacturer such as JSB). There is probably a head size sticker on the back side of the container (e.g. 4.49, 4.50, 4.51mm). Wadcutter pellets such as these were likely purchased for use with a 10 meter target air rifle or air pistol. How much are these worth? Not a great deal as there are relatively few of them in a package and would have value to someone who has a air gun that can shoot these particular pellets accurately.
