LOS ANGELES (AP) — “Friends” memorabilia, artwork and other valuables from the estate of Matthew Perry are being put up for sale at an auction to benefit the charitable foundation established in the actor’s name soon after his 2023 death.

The June 5 event put on by Heritage Auctions will benefit the Matthew Perry Foundation, which works to destigmatize addiction and aid in recovery from substance abuse.

“Matthew believed addiction should be met with compassion and science, not stigma and silence,” the foundation’s CEO Lisa Kasteler Calio said in a statement. “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.”

The auction site opened Tuesday. Items will be on display from May 18 to May 29 in Beverly Hills before the June 5 auction that will take place at Heritage Auctions’ Dallas showroom and online.

Net proceeds will go to initiatives supported by the foundation. They include the Matthew Perry Fellowship in Addiction Medicine at Massachusetts General Hospital, grants to organizations that work directly with recovering addicts, and Healing Appalachia, a recovery-focused sober music festival.
