Dirt Cleaner

Thanks! This one belongs to a friend who wanted to know more about it. It is a good looking marble.

Hoping to find out something about this one. 27mm, just over 1" diameter. One side is a little rough.

Bought this huge lot at a live auction on Jan 1. I heard they had a bin of marbles so I dared to go out in the crowd. I have not looked past what was on top but one day in the near future I will make a video going through the entire bin.
