Who knew jeans tucked away 124 years ago in a trunk would someday be worth so much today? The oldest pair of Levi Strauss blue jeans known to exist are from the 1890s and in pristine condition. They are believed to have never been worn. The Levis are expected to go for $80,000, according to auctioneer Daniel Soules. The jeans also come with a Levi's guarantee referencing a dark chapter in American history. They were owned by legendary pioneer Solomon Warner who helped settle Tucson, Arizona.
