A 1952 Topps Mickey Mantle graded PSA 8.5 sold for $810,000. A PSA 8 copy went for $420,000. Both were the top baseball card sales during Heritage Auctions’ 2018 Summer Platinum Night Sports Collectibles Auction.

All top six cards sold for more than $100,000.

The PSA 8.5 copy is part of a newly uncovered stash of long-forgotten vintage cards two brothers had since their childhood. It’s one of five second-year 1952 Topps Mickey Mantle cards in their collection.

It’s one of five to have the NM-MT+ 8.5 grade from PSA. The 1952 Topps Mickey Mantle has just six PSA 9 and three PSA 10 copies. The highest grade for a BVG copy is an 8.

For price comparisons, a PSA 9 Mantle sold for $2.88 million this past April, also through Heritage Auctions. That particular card was owned by former NFL player Evan Mathis.

Here’s a list of all of the cards to sell for more than $100,000 during Heritage’s sale.
