Found in 1937 in the Alma District, Park County Pennsylvania Mountain, this nugget weighs in at an impressive 12 Troy Ounces.

On July 23, 1887, Tom Groves and Harry Lytton struck it rich — they found the largest piece of gold ever discovered in Colorado, a record that stands to this day. The discovery happened in the Farncomb Hill area, outside of Breckenridge, and after finding the piece of irregular massive gold, Groves wrapped the 13 ½ pound chunk in a blanket, parading it around Breckenridge — thus earning it the nickname of “Tom’s Baby.”
