When did kids quit playing with marbles? I am packing for a move next month and ran across an old bag with hundreds of marbles in it, that I had forgotten I even had. They are at least 40 years old, some quite older. I haven't seen kids playing with these things for many years. Do kids anywhere still use them, or are they a victim of the digital age? I wonder if they are collectible or worth anything. Does anyone know anything about these bad boys?
