Very cool marble. Has a nope niple like cut mark or cold roll.  I believe it's a cut mark. I had to really light it to to show the detail within. Very dark appearance which i show in the pictures.

I like this type--I think that it is a dug WVS--probably an Alley Agate.

I thought Vacor at first but they seem to have better grading than this one has.

The damage on this one along with the out of roundness suggest what I think is right.

I appreciate all opinions and hope to see some more.

Marble--On!!
