"The first Lincoln County Courthouse, also known as the Pioche Courthouse and the Old Lincoln County Courthouse, in Pioche, Nevada earned the title "Million Dollar Courthouse" after it cost $75,000 to build in 1872, an amount equivalent to over $1 million in year 2000 dollars for a relatively small building. With added costs attributed to finance charges and fiscal mismanagement, the cost in 1872 dollars came to over $800,000, or more than $11 million in year 2000 dollars. The debt incurred by the county was not retired until 1938, when the new courthouse was under construction."
