WARNING! This certificate is completely fake, as is the Luigi Raybaudi signature on the certificate and the Maurizio Raybaudi signature on the piece. This “item" is being offered in an online auction ending May 30, 2026. Il “pezzo” è offerto in un’asta online con scadenza 30 maggio 2026.

The Raybaudi Studio represented by Serena Vignati is a founding member of the APFIP (Association of Italian Professional Philatelic Experts), affiliated with the AIEP (Association Internationale des Experts en Philatelie) Beginning in 2026, the Association has decided to issue certificates to its members with a numbered holographic stamp, with separate numbers for each expert. Our certificates issued from that date therefore feature a progressive number at the top left and a holographic stamp with the same identification number at the bottom.

Studio Raybaudi also offers the option of updating certificates issued since 2012, ori- ginally bearing only Serena Vignati's signature. Following a specific verification, the originality and state of preservation of the specimen can be confirmed by placing a countersigned stamp on the back of the certificate, provided the information is consi stent with the declaration from the original issue.
