Estimate of stamps, postcards, shares and old documents

Old Stamps and Documents

AZ Auction is an auction house where our experts and specialists offer free appraisals of your stamps, postcards, stock, and old documents, online and by appointment.
Our appraisals are free, confidential, and without obligation. They can be used for estate planning, in preparation for a potential sale, or simply for informational purposes.

Specializing in philately and philatelic news, the AZ Auction team, assisted by Daniel Berrous, appraises your collections of stamps, postcards, stock, and old documents from all centuries and eras (French, Belgian, Orval, and Chinese stamps, registered letters, philatelic albums, postal balloons, correspondence, Monaco, overseas, and Liberation stamps, stamp folders, colonial stamps, archival mail, active letters, Chinese, 19th-century, 20th-century, Dutch, Russian, American, British, former colonial, and overseas stamps, etc.).
Our free appraisal of your stamps, postal archives, postcards, stock, and old documents also includes verification of their authenticity.

If you wish, we can also offer your stamps, postcards, stock, and old documents for sale at our upcoming themed sales, guaranteeing you the best price. Under certain conditions, we also come to your home and organize real estate appraisal days in various regions and cities across Belgium, led by our expert, Daniel Berrous. Our real estate appraisal sessions take place on Mondays from 2:30 p.m. to 5:00 p.m. at our Brussels offices, without an appointment.
