About our Mineral Experts
Due to his experience, Luca Esposito is the ideal auctioneer for the Mineral auction. Through his network, he stays in touch with trusted sellers and knows exactly what the market has to offer.

For Trevor Boyd, a job as auctioneer at Catawiki felt like a natural transition. He enjoys his passion every day. At the same time, he puts Catawiki on the map in Ireland and the UK. He does so personally through exhibitions, but also by creating the most popular auctions.
