Heritage Auctions will host the sale on 5 June at its Dallas showroom, with online bidding also available. The auction site opened on Tuesday, and items will be on public display in Beverly Hills from 18 to 29 May before the gavel falls. Net proceeds will go to initiatives supported by the Matthew Perry Foundation, which was established after the actor’s death in October 2023 to destigmatise addiction and aid recovery from substance abuse.

Among the most significant lots is the original script for the Friends pilot, dating from when the landmark sitcom carried the working title Six of One. The script has been signed by Perry alongside his co-stars Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer, and was donated to the auction by Warner Bros, the show’s producer. Bidding starts at $500 (c. £370).

A separate bundle of 26 of Perry’s personal Friends scripts opens at $1,000 and features pages from several beloved episodes, including The One With Ross’s Tan, The One Where Joey Speaks French and the two-part series finale.

Fans of the show will also be drawn to Perry’s personal replica of the iconic yellow peephole frame that adorned the door of Monica and Rachel’s apartment, as well as his 1995 Screen Actors Guild award for best performance by an ensemble in a comedy series.

The actor’s love of all things Batman is reflected in two further lots: a Batman wristwatch and a custom Batman ping-pong table, the latter offered without its net.

The headline piece from Perry’s art collection is an original Banksy expected to sell for more than $800,000. Also on offer are framed handwritten lyrics by the Australian rock group Little River Band, The Guardian reports.

Lisa Kasteler Calio, chief executive of the Matthew Perry Foundation, said: “Matthew believed addiction should be met with compassion and science, not stigma and silence.

“This auction fuels the foundation’s work to expand access to evidence-based care and confront stigma. It is one more way we ensure that no one has to fight this disease alone.”
