A Harley-Davidson motorbike sold at auction on Thursday for almost 20 times its estimated value – because its previous owner was the pope.

Signed “Francesco” on its tank, the Dyna Super Glide sold for 241,500 euros ($328,300), with a Harley-Davidson leather jacket, also signed by the pope, going for 57,500 euros, both to anonymous bidders, auction house Bonhams said.

“It has to be a world record for a 21st century Harley-Davidson and certainly for a Harley-Davidson leather jacket,” said Ben Walker, head of motorcycles at Bonhams. The motorbike had a pre-sale estimate of 12,000-15,000 euros.

The items were presented to the head of the Roman Catholic Church last June by the manufacturer to mark the U.S. brand’s 110th anniversary.
