The way supply and demand come together at Catawiki is fascinating.
When an important Roman excavation takes place in your aunt’s cellar, it makes sense to take an interest in archaeology. That is precisely what happened to Willem Knapen. As a child, he followed the excavation closely and saw a lot of coins and other objects pass by. He soon started going to all the coin and archaeological fairs and auctions in order to build up his own collection. After spending years studying Egyptology and doing volunteer work at the Rijksmuseum van Oudheden (National Museum of Antiquities), Willem worked as an auction employee at an auction house in The Hague. He started out as a jack of all trades, but he increasingly helped with the description and assessment of objects.
So Willem landed in the auction world, and Catawiki is now lucky to be his current employer. His experience and knowledge of coins are crucial in his current role as the Antique Coins auctioneer, both to weed out forgeries and to put together as varied an auction as possible, preferably ranging from affordable late Roman coins to more precious early Greek drachmas and staters. His personal preference is for early Greek coins, such as those from Aegina, Syracuse and Bruttium, which are usually small works of art in and of themselves. Willem is happy to include them in his auction if they are still in excellent condition.
