Letter of Opinion (LOO)

This is a rejection letter indicating that the autograph did not meet the standards set by our experts. The Letter of Opinion (LOO) reflects the consensus of our experts that the authenticity of the autograph is questionable. The LOO also outlines specific reasons for this conclusion, highlighting any inconsistencies or irregularities detected in the signature

Clubhouse Letter (CH)

At times, autographed memorabilia may be signed by someone else without any malicious intent. These individuals, known as “ghost signers,” can include batboys, secretaries, clubhouse staff, or even family members signing on behalf of the intended signer. To distinguish between these non-malicious (ghost-signed) signatures and genuine autographs, we provides a customized "Clubhouse" letter, clearly identifying the difference

Inconclusive Letter (INC)

In rare instances, determining the authenticity of an autograph may be inconclusive. Even after thorough examination, our authenticators may be unable to reach a confident consensus, and therefore, no definitive opinion can be provided. If your item falls into this category, we will issue a credit voucher for the full authentication fee, which can be applied to a future submission
