According to Hicham Aboutaam of Phoenix Ancient Art, collecting and owning antiquities has always been an interest to people throughout history. Antiquities are appreciated for their beauty as art objects as well as their role as repositories of the cultures of the progenitors of western civilization. For this reason collecting antiquities is a growing interest, and if the number of objects can never get larger, as demand increases and supply is static, prices will rise. This fact makes investing in antiquities a pretty safe bet.
In other words, as Hicham Aboutaam puts it,
“Especially antiquities originating in the area of the Mediterranean basin are the essence of our western civilization.”
