Through a conversation with Amalia Dayan, partner at Lévy Gorvy Dayan and former Phillips specialist, this article examines how auctions shape private value, how shifting market conditions are changing the role of galleries, and why questions of quality, scholarship, and historical positioning have become increasingly central to the contemporary art market. Moving between market data and the rediscovery of artists such as Domenico Gnoli, the piece considers an art world increasingly concerned with proof, endurance, and the construction of value.
