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 US soccer player Mia Hamm sold in June.
"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-equaling 24th Grand Slam title, has not competed since limping out of her first-round match at Wimbledon in August.
