The owner of one of the four cards graded 2.5 by PSA has consigned it to Heritage Auctions’ Winter Platinum Night sale on February 25-26.
In October, Robert Edward Auctions offered the first of the seven rare Cobb cards to be offered at public auction. The PSA 1.5 sold for $192,000.
The pre-sale estimate on the 2.5 is $300,000+. The current Sportscard Market Report value is $350,000.
Not long after the seven cards were discovered in an old paper bag early last year and quickly graded, they were placed for sale by MINT State, a South Carolina-based dealer. The highest graded example, a 4.5, sold for an undisclosed seven-figure price.
Two of the cards, a 3.5 and another 2.5 are currently being offered on eBay by MINT State.
The Heritage auction will also include a PSA 8 1952 Topps Mickey Mantle
