This is some more of the stuff I have aquired over the years including some old marbles, a Mammoth vertibre and tooth, some gold flake and a few other little things.
Cool stuff. The marble on the far bottom right that is black is called an indian. It's hand made. If you hold a light to it and can see light through it then it's called a mag-lite indian which is a little more valuable. Your other marbles all look like clay marbles. Thanks for sharing with us. Paul
