There are now three PSA 10 Sandy Koufax rookie cards.
On Wednesday, company president Joe Orlando tweeted an image of the card, which indicated it had just been graded and authenticated.

There was no word on who submitted the card or whether it might be heading for auction.
Of the more than 126,000 1955 Topps cards PSA has examined over the years, just 58 have been rated a 10. Of the 5,000 Koufax cards, just 23 rated even as high as a 9, but the card does share the highest population of 10s with #103, Charlie White.
The other two major rookie cards in the ’55 set, Roberto Clemente and Harmon Killebrew, have a population of one 10 each.
The PSA 10 Clemente rookie was at one time owned by former big leaguer Dmitri Young, who sold his collection of Hall of Fame rooke 10s via SCP Auctions in 2012. The Clemente card was purchased for $432,960. There are 11 PSA 9 Clemente cards on the PSA Population Report.
A PSA 9 Koufax sold in May of last year for $44,812 via Heritage Auctions, more than double what they had been bringing at the turn of the decade.
