Stamps brought to you by Matthieu Schoemaker
“Honesty and equality last the longest.”
Matthieu began collecting stamps at the age of five, captivated by the colourful designs arriving with the daily mail. His early fascination soon evolved into a focus on deviations from the norm—plate errors, perforation varieties, gum types and unusual cancellations. By thirteen, his advanced knowledge of Dutch definitives earned him a place in the adult division of his philatelic society. Professionally active since 2011, he built his first website in 2009 and has traded extensively at fairs and online. In 2022, he fulfilled a lifelong ambition by publishing the 1,000-page Mast Plate Errors Catalogue. Since joining Catawiki in September 2025, he has brought deep market knowledge, strong industry contacts and a commitment to accuracy, ensuring high-quality auctions featuring exceptional and unusual material.
