]So, I have been collecting marbles when I metal detect. I came across this bag of marbles. I look on line and I just can't figure out marbles. How do I know if I have a collectable or vintage? Thanks for your help.
Going marbles.
Most of those are modern marbles imported from Asia. In the last photo, the black and red one is an American one made by Marble King but still not very old. The other two with red and the brown ring around the red are Vitro black line all-reds. Those are probably 1970s-80s and also made in the U.S. I'd say all of them are from the 1970s to near present.
