Steve Jobs, Geronimo, Bruce Lee, John Adams, and Marilyn Monroe among inaugural RR Auctions PSA Encapsulated Auction. Ends Sept 22.

RR Auction's inaugural PSA Encapsulated Auction brings a treasure trove of nearly 700 slabbed items to the auction block—a diverse assortment of material ranging from straightforward signatures to iconic photographs to content-rich letters and documents.

Among the highlights is an early Steve Jobs autograph signed quote," Go change the world! steve jobs." A sought-after quote that is now synonymous with Jobs, whose prophetic message influenced notable Generation X-ers such as Larry Page, Sergey Brin, Jeff Bezos, and Elon Musk to truly "change the world!." (Estimate: $6,000+)

A rare Geronimo signature that bears pencil notations is "9/1904, St. Louis World Fair." Geronimo had been at the World's Fair in St. Louis until early October when he returned to his home at Fort Sill. (Estimate: $4,000+)

A Bruce Lee signed photograph as Kato in The Green Hornet, his first TV role. In addition to the neatly signed and inscribed message, Lee added his 'Loong' character below his signature, representing the Chinese character of a dragon. (Estimate: $15,000+) 

An important autograph letter signed by John Adams. The handwritten letter from Paris during negotiations to end the Revolution, dated May 26, 1783. Autograph letters from Adams to Hancock are exceedingly rare: in 1987, R. A. Ryerson, editor of the Adams Papers, identified this as one of only 13 extant letters of Adams to Hancock. Nine of these are in the Adams Papers, other institutions own three, and only one other item—an account statement—remained in private hands at that date. (Estimate: $35,000+) 

And a beautiful Marilyn Monroe signed photograph. Vintage matte-finish photo of Monroe reclining on a pillow and wearing a low-cut dress and diamond jewelry, a pose from circa 1953. A classic, virtually pristine portrait of the blonde bombshell flashing her radiant smile. (Estimate: $20,000+) 

Other top autographs include Al Capone, Mohandas Gandhi, Jimi Hendrix, the Beatles, John Dillinger, Paul Revere, Bruce Lee, Winston Churchill, and Pablo Picasso. Every item in the sale has been encapsulated by PSA, the largest third-party authentication company in the world.

"We're thrilled and excited to bring this remarkable collection — our first all PSA encapsulated historical autograph auction ever held," said Bobby Livingston, Executive VP at RR Auction. "Curated over the last six months — the majority of the autographs have been freshly submitted and encapsulated by the worlds leading authentication company." 

The PSA Encapsulated Autograph Auction by RR Auction began on August 12 and will conclude on September 22.
