A: Stamp values depend on a number of factors.  The first step in evaluating a stamp value entails proper identification.  U.S. stamp dealers generally use the Scott Standard Postage Stamp Catalog for stamp classifications.  Most libraries have a complete set (6 volumes) in their reference section.  Earlier U.S. stamps are often very difficult to properly identify and expert advice may be necessary.

(Please note: County Stamp Center purchases collections and is not interested in evaluating or appraising individual stamps.  Please not submit inquiries requesting values for individual items.)
