How to Research an Artwork: Appraisal


When trying to ascertain the value of your artwork, auction records for that particular artist can be useful.  Most websites require a subscription to view their price databases and auction records, but they also provide additional, free information.  If nothing else, you can determine whether your artist has any auction records, even if you can’t see the prices those works realized.

New York Public Library, Auction Sales Indexes
New York Public Library guide to auction sale indexes, price guides and catalogs. Because individual auction houses do not issue their own indexes, the use of these compilations provides the best approach to finding sale information. Each index provides different coverage in terms of dates, contents and scope. 


Condition also affects the value of artwork, and being able to identify condition problems can assist in the appraisal process.
