A vintage pair of Levi’s from the 1880s found down an abandoned New Mexico mine have been sold at auction for $87,400. They are now among the most expensive pair of jeans ever sold.

The pair of jeans would have been worn by a miner from the authentic gold rush era and have been described as the “holy grail of vintage denim collecting.”

They feature suspender buttons on the waistband, selvedge denim badges, a single back pocket and wax flecked over the legs from where the original owner labored under candle light.

The winning bid was $76,000, but after buyer’s premiums the total for the jeans came to $87,400.
