Every 70-year-old relic has a story. This 1952 Topps Mickey Mantle has one that's better than most. Sitting in a Boston basement for decades after a botched delivery attempt, a case of 1952 Topps was happened upon by notable collector Mr. Mint in 1985. Inside were multiple outstanding examples of the '52 Mantle, including this exact one, which Mint considered the "finest known example in the world". It was sold to the current owner for $50,000 at Madison Square Garden in 1991, with proof coming in the way of a signed copy of Mr. Mint's Insider's Guide to Investing and a letter from the storied collector. Graded a 9.5 by SGC, it's up for auction and has a chance to beat the all-time record of $6.6 million, currently held by a 1909 Honus Wagner card that sold for that amount in 2021.
