Just a few months ago, few soccer fans outside New Zealand knew Tim Payne’s name. The shirt Payne wore in his debut for Club Olimpia, a Paraguayan soccer powerhouse, has become a coveted piece of match-worn memorabilia since the club put it up for auction online five days ago. With bidding set to close Thursday, the leading offer has climbed above 21 million in Paraguay’s currency, the guarani, equivalent to around $3,270.
