Rare stamps of premium quality

The experts might accept faults depending on the value and the rarity of the stamp. The rarer the stamp is, the more the expert might accept more serious faults (fold, small or cut margin, short or missing perforation, no gum while expected, stain on the gum).

Authenticity/Certification Requirements

Buyers are more likely to bid on your lot if they know it is certified as being authentic. This is why we ask for certificates from trusted third-party experts if there is a doubt about the authenticity.

  • If there are any doubts about the authenticity of the object, the expert will ask for certification.
  • If the stamp comes with a certificate, the expert will first check the coherence between the item and the description on the certificate. In case of incoherence, the expert will ask for another certificate.
  • If there are any doubts about authenticity/forgery of a signature or certificate, the expert will ask for a new signature/certificate.
