NIA has acquired a unique database of the world's important works of art that regularly appear at auction. Our primary database contains over 50 years of these auction results, covering almost 3 million works of art, by more that 250 thousand artists from 450 different auction houses around the world.

Other databases fill a key need in helping evaluate art that is not handled by international auction houses. This non-auction art represents 98% of art work bought and sold annually.

NIA Certified Appraisals have been specifically designed to meet the requirements of insurance providers.
