In Season 3 Episode 20 of Family Matters, Steve Urkel offers singer Johnny Gill a mint 1952 Topps Mickey Mantle in exchange for appearing at the Winslow household to impress Laura. I‘m not sure what the going rate was for a PSA 9-ish Mantle in 1992, but that would be a $3 million deal today.
Would you rip? Unfortunately we don't know if its Series 1 or 2. This is key because depending upon the series, it could be high or low numbered cards where the high numbered contains the Mantle and Jackie.
My sense is its worth more sealed because the enterprise value of it, the potential, is worth more than the risk of opening it and it being a series 1 pack.
I've always loved the mental games one goes through on vintage sealed packs or boxes and the price of it and the implied potential value.
