A digital copy of “Back to the Future” will set you back about $15 on iTunes. Real BTTF nerds might spring for the complete trilogy in its limited edition steelbook form, now $70 on Amazon. But if you really, really want to prove your bonafides, you need to own it on VHS, for which the market has likely ballooned now that a copy was sold by Texas’ Heritage Auctions for $75,000.
Granted, the one sold last week is far from a normal VHS. First, it’s sealed in its original Shrinkwrap, including the white MCA Home Video watermark, making it an even rarer collectible given that the classic time-travel comedy starring Michael J. Fox as Marty McFly is now 36 years-old. Second, this specific copy of the film was auctioned by its original owner, actor Tom Wilson, who played a history book’s worth of McFly family bullies throughout the films, most notably Biff Tannen.
