One of the largest gold nuggets ever found in western South Dakota's Black Hills is now on permanent display in Deadwood.
The Potato Creek Johnny gold nugget is housed in a $4,000 bulletproof display case at the Adams Museum. The case was paid for with money from the sale last fall of a replica of the nugget.
John Perrett found the real nugget on his claim on Potato Creek on May 27, 1929. It weighs nearly 7.4 troy ounces. Adams Museum founder W.E. Adams bought the nugget for $250 in 1934.
Exhibit Curator Darrel Nelson says that historically, the value of the nugget is priceless.
