While panning on May 27, 1929, Potato Creek Johnny uncovered a
gold nugget, one of the largest ever discovered in the Black Hills. In 1934, local businessman W.E. Adams bought the nugget from Johnny for $250 and put it on display in the
Adams Museum. The authenticity of Potato Creek Johnny's gold nugget has been the subject of debate. Several local residents suspected that Johnny had created the nugget by melting down smaller quantities of gold into one piece; some accused him of having stolen the gold to do so. Analysis of the nugget by various gold experts have determined the nugget is likely to be authentic, due to the presence of natural quartz crystals inside. and became a feature of
Deadwood's Days of '76 celebrations in subsequent years. In 1939, he was pictured in
Life magazine. ==Personal life==
