This cone is open pontilled and has the "X" embossed on the base..Mint, too. I dug it in an old basement of a 3 1/2 story ship captains home. Got some other beauties that day too.
These all came from the same dig, all are pontilled and mint, plus a pontilled Harrison's Columbian Ink, in aqua, which I sold for some reason. I never researched the captain. Maybe I should this winter.
Wicked cool, I have one too but it's got fractures in the lip. Maybe a bit darker in color. Nothing broken or glued but folks want perfect. Ya can't have any 200 year old mistakes fowling up the product. I couldn't get $35 and wont bother selling it now. You should make out well but it looks like a keeper to me.
I don't believe I could ever sell these four. It was a great day digging with my brother Dave, and finding this type of glass in this condition is so rare.
