An autographed Serena Williams rookie card printed in 2003 has become the most expensive women’s sports card after fetching $44,280 at auction last weekend, New Jersey-based Goldin Auctions said. The previous record was $34,440 for a rookie card of former U.S. soccer player Mia Hamm sold in June. ESPN reported the Williams card was bought by alternative-asset trading platform Alt on behalf of a private client. “People are accepting women’s trading cards as collectables,” ESPN quoted Goldin Auctions founder Ken Goldin as saying. The 40-year-old Williams, who is still hunting a record-equalling 24th Grand Slam title, has not competed since limping out of her first-round match at Wimbledon in August. By Manasi Pathak
