Mike:
   
  I would say definitely something man made.
   
  Perhaps from a mill or a factory that makes glass and glass products. They could also be iron from slag. I have a piece of slag that consists of a grayish glass like substance with perfectly round pieces of iron in it. I got it years ago at a rock shop.
   
  I don?t understand why he calls then magnetite (perhaps some stick to a magnet).
   
  I looked at it again ? I think by products from some sort of glass producing factory. If they got into a stream, they could travel a long distance. I don't think a rough piece of material would become this round by being in a stream - I would say they were that way before they got there.
   
  They look interesting ? guess it will cost you $7.00 + shipping to see them.

I'm not trying to be funny or sarcastic; the photo
with the auction is pretty interesting. Would sand
actually round and polish itself this well in a stream
bed?
I believe this is not meteorite related- but what
really is this material?

Thank You
Mike
