Judged as “very good/excellent” by Beckett Grading Services, Roberto Clemente’s 1955 Topps rookie baseball card just sold at the Detroit City Sports Memorabilia Auction on Saturday, May 21, for $1,607. And this is before the 20% buyer’s premium, sales tax, and shipping add-ons, of course. However, anyone with access to the “Flux Capacitor” featured in the wonderful time-travel movie BACK TO THE FUTURE (1985), can return to 1955, and buy this card, for the original asking price. Back then, it cost baby boomer kids — now wait for it — a single penny, at your local grocery store. One cent. Any investment, anyone ever made, in Roberto Clemente, always paid off. Big time. Still does.
