A sharp, robust twinned copper, complete all around and from top to bottom! This is the classic material found here in a few famous erratic discoveries, in the early 2000s. The specimen was self-collected at the time with his old digging friends, and long kept here in the private collection of Dallas dealer Doug Wallace (he is around 80 now, and kept only self collected minerals from his various projects over the years). This is a relatively large example, as thousands of smaller specimens were recovered but this size produced fewer, and so long ago.
