Here`s a big old CD 136 with the crown embossing B & O on one side and PAT. JAN 25th 1870 on the opposite side. The color is a light bluish aqua. The embossing is pretty strong. There`s a few white strings floating around along with a few decent size bubbles. Bright light brings out a ton of micro bubbles too. There is just a bit of plier roughness at the left side mold line and one flea tick on the side of the dome. This sturdy old soldier is yours for $25 plus shipping.
