Ex. David P. Wilber Collection

For most serious collectors of radioactive minerals, the classic “gummite” specimens from the Ruggles mine in New Hampshire need no introduction. This is a much better than average example with BRIGHT colors, a beautiful polish, super rich as seen. Has several old collection numbers on it. HOT as well, over 150,000 CPM on my Ludlum Model 3 counter. This material in this quality has become very uncommon!
