NIA Research and Documentation

The National Institute of Appraisers (NIA) has amassed an unparalleled computerized database on the world's important works of art that regularly appear at auction. Our primary database has the results of over 900,000 works by nearly 80,000 artists. Results from 500 auction houses throughout the world are documented. 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 carriers and our Certified Appraisals for fine art donations are based on the latest Internal Revenue Service regulations.

The NIA appraisal is based on Fair Market "Replacement" Value. It is the price the art would sell for on the open market. It is the price that would be agreed on between a willing buyer and a willing seller, with neither being required to act and both having a reasonable knowledge of the relevant facts.


NIA has appraised thousands of private, corporate and municipal collections, nationwide. Our appraisers are regularly called upon to consult with government agencies including the IRS, FBI, RTC, DEA and the US Marshall's offices.


NIA has a preprinted fee schedule and fees are based on a flat fee-per-item schedule, determined and paid for in advance.
