Having tried to flog the Pawn Stars a DeLorean before — and claiming to have sold it himself for a healthy profit — the seller is confident he can convince them to hand him $7500 for the iconic prop. It's signed by several stars: writer Bob Gale, Doc Brown actor Christopher Lloyd, and Tom Wilson, who plays the almanac's villainous guardian, Biff.
The team consults "Back To The Future" prop master 'Dangerous' Bob Widin — dubbed as such by Steven Spielberg — to check the almanac is legit. It is indeed, with Bob confirming its official status as one of 24 screen-used copies from the film. Fascinatingly, it's tiny tell-tale signs that prove it to be the real thing — like the marks from the tape applied by Bob's own hand to stop the covers coming loose on set. But one detail limits the impressive item's value.
Surprisingly, the signatures on the almanac actually decrease its value, rather than adding to it. "The real collectors," Bob says, "want an absolutely pristine prop", so the stars' squiggles are a turn-off for many potential buyers. Disappointingly for the seller, Bob values the prop at just $2500. Looking to make a profit for themselves, of course, the Pawn Stars offer $1500 — a disappointing $6000 drop from the asking price. The spurned seller slinks away, but as Rick quips at the end of their exchange, "Maybe it'll be worth something in the future."
