A 5,200 carat, $156,000 Cody Stone was donated to the Buffalo Bill Museum.
The stone came from a gold mine in Arizona once owned by Buffalo Bill Cody who spent some of his childhood in LeClaire.
Jackie Lee discovered the stone in 2010.
"I mined the milky quartz ore with a trusted friend from the Cody Tunnel in the Santa Catalina Mountains just outside of Tucson."
Lee's business partner, Loren Breckenridge from Appleton, Wisconsin, says the Cody Stone is historically significant.
"Buffalo Bill was out doing his Wild West Shows, and while he was gone his employees were stealing from him, and we actually have documented proof. We wanted to put the stone in a museum with the promenades so people know the true story."
Cody Stones, also called Milky Quartz Ore contain gold, silver, copper, and tungsten. The mine has since caved in and is now a part of the Coronado National Forest in Arizona.
