Ghost-Signed
An item signed by someone other than the person it's attributed to.
A ghost-signed item is one where the signature was applied by someone other than the person the autograph is attributed to — typically a teammate, coach, assistant, or family member signing on their behalf.
Ghost signing differs from secretarial signatures in that ghost signers may be peers or associates rather than administrative staff. For example, a coach signing a player's name on team equipment, or a band member signing another member's name on a group item.
Ghost signing has been documented across all areas of collecting — sports, entertainment, and politics. Some ghost-signed items are the result of innocent convenience (a teammate helping out), while others are deliberate deception.
Detection of ghost signatures requires comparing the questioned signature against known authentic examples. Ghost signers rarely replicate every nuance of the original signer's handwriting, leaving telltale differences in letter formation, pen pressure, and flow.
Like clubhouse signatures and secretarial signatures, ghost-signed items are considered non-authentic and carry no collector value. Professional authentication from PSA, JSA, or Beckett is the best way to avoid purchasing ghost-signed items.
