About 24 hours after a PSA 8.5 1952 Topps Mickey Mantle sold for $810,000, another example the same card deemed a half-grade lower brought a price about half that amount as Heritage Auctions wrapped up its Summer Platinum sale late Sunday night. The sale illustrated the demand for the card at the highest levels. While 34 unqualified 8s exist on PSA’s Population Report, only 14 rate higher (there are five 8.5s).

The $420,000 winning bid, which included a 20% buyer’s premium, marked the eighth time since 2015 that someone paid $400,000 or more for PSA 8 ’52 Mantle at public auction, but the first since November of last year.

In all, the two-day auction realized nearly $8.6 million, topped by Saturday night’s $1.32 million sale of a 1964-65 Mantle jersey believed to have been used when he hit the final two World Series home runs of his career. Heritage says the result marks just the fourth seven-figure sale of a game-worn jersey in sports collectibles auction history.

Among the other items sold Sunday was a cracked 1960 Mantle bat, rated GU9 by PSA/DNA with provenance from the son of a former member of the Yankees TV broadcast crew who had fished it out of a discard barrel in the dugout. It went for $43,260. A basketball carrying autographs and uniform numbers of all of the members of the 1992 US Dream team accumulated by former NBA writer and broadcaster Peter Vescey sold for $33,600 and one of only six known ticket stubs from Michael Jordan’s first NBA game in 1984 netted $33,600.
