Wow - this specimen, personally collected by RJ Waidler as a teenager from this historic mine opened in 1960 by New Jersey Zinc Company. By most standards and considering all the Galena localities in the world, this appears to be just another Galena specimen. It is NOT. It is an exceptional piece from this historic district and mine. The district itself dates back to 1827, when lead was discovered in Wisconsin. The specimen is a dull gray, but with NO damage and of the cubic faces. There are slight modifications to the corners. It is not dirty. I have cleaned it but preserved the mine-run tarnished and coated exterior as it should be preserved.

It is heavy and may cost extra to ship.
