If you have a research project or are preparing an article, the Authentication Service may be able to help. Information on all completed items submitted for authentication can be retrieved by certificate number, town postmark, addressee name and town, catalog number, or other key fields. In some cases, scans of these items may also be available.
Currently there is no charge for this service to CSA members and individuals who are conducting an Institute for Analytical Philately (IAP) sponsored project. For all others, there is a minimum charge of $5.00. For further information, contact John L. Kimbrough MD at 10140 Wandering Way, Benbrook, TX 76126 or E-mail firstname.lastname@example.org for further information.
