  • paintings, reliefs or statues without proof of authenticity
  • items produced in large numbers after 1945 (particularly medals and uniforms) are of little interest to collectors

    banners from political organisations such as NSDAP, SS, SA or Hitler Youth

 3. Proof of Authenticity / Certification Requirements

Buyers are more likely to bid on your lot if they know that it’s certified as being authentic, particularly for lots of higher value.


In case of doubt, our in-house experts may ask for a proof of authenticity:

  • in the form of  a third party certificate
  • a supporting photo of a UV light test
  • record of ownership accompanied by supporting documentation, such as receipts or original certificates

Such certificates can be obtained from a number of the trusted external experts

(please see suggestions below).

Suggestion for trusted experts providing third party certification

Particularly for items originating from WWII, Catawiki has a list of suggested external experts who’ll provide a digital certificate. These experts typically provide a certificate within 7 days at a standard cost of €30.
