MEMPHIS (AP) — Elvis Presley’s Graceland is planning an auction of artifacts to be held during the late entertainer’s 85th birthday celebration on Jan. 8.

All the items up for auction come from third party collectors but have been thoroughly researched and certified by Graceland Authenticated, according to a news release from Elvis Presley Enterprises, Inc. The mansion and all artifacts in the Graceland Archives continue to be owned by Lisa Marie Presley and are not for sale.

Items to be included in the auction were announced on Monday along with registration information. The catalog is available at Graceland’s official online store.
