Alley, Ron seen it and thought it was a swirl carnival type. He said the same thing I did, "not gonna find another like that" Thing sticks out like a sore thumb. Chuck called me a "Sandbagger" (holdout) when I posted it on AAM last year
How big it is will tell you if it's a toothpick holder, looks as tall as a pop bottle from the pix, a little to big for a toothpick holder if it's that big. Maybe put your hand by it or tape measure for height definition to see how tall it is.
Sorry, I can't tell if it's damage or a pontil. If it's a pontil you're right, if it's fractures or a chip it's machine made. This is what I can't quite make out.
