Since 1989 Bill Jackson and Alex Przygoda at Jackson Galleries have been providing professional Authentication to the Prehistoric Antiquities Market. Our non-destructive method known as Analysis of Post-Depositional Surface Modification, or PDSM for short, has become an international ‘gold-standard’ for the examination of not only Native American Prehistorics, but PreColumbian, Egyptian, Roman, Oriental, and African antiquities as well. Along with his stepson, Alex Przygoda, he has provided these services to over 8,000 customers on 5 continents. In 1996 he started offering unique one-on-one training classes for collectors to learn the methodology, which utilizes stereo-microscopy and ultraviolet analysis techniques. Since then he has trained over 400 collectors and 25 Federal and State Archaeologists with the National Park Service, Bureau of Land Management, and Tennessee Valley Authority and other agencies.
Evaluation Overview
Jackson Galleries is Internationally known for our objective, unbiased, scientific approach to Artifact Authentication. We pride ourselves on our commitment to letting the artifacts themselves tell us if they are authentic, not hearsay, rumor, stories or associated provenance. Our well-founded artifact authentication method is reliant on a scientific methodology based on known facts compiled and corroborated by numerous related scientific papers by geologists, microbiologists, archaeologists, forensic scientists, and other related fields. We microscopically examine each and every artifact for specific geologic criteria, as well as evidence of modern manufacture or enhancement. Upon completion of the evaluation, either a Certificate of Authenticity is issued, or a detailed letter describing our findings is issued, with copies kept at our location to ensure accuracy and to prevent forgeries.
The Method: Analysis of the P.D.S.M.
Simply put, our method, known as the Analysis of the Post-Depositional Surface Modification, is basically understanding and identifying through optical means all of the geological processes, (physical, geo-chemical, biological) that occur to an artifact once it is deposited on or in the ground. Specific environmental variables affect a given material in very specific and measurable ways no matter where on earth those environmental variables occur. Under the microscope, we can see these affectations as they present as weathering patterns on the flint itself, or as mineral growths on the surface which are consistent with the environment in which the piece was found. Every material we examine has a specific well-documented model of what happens to it in the natural environment, and when something is out of the ordinary, more often than not there is evidence of modern manufacture which can be determined to be the root cause. Similarly, modern manufacturing techniques leave their own specific marks upon the item no matter how hard fakers try to mask them.
To date almost 50,000 Certificates of Authenticity have been issued, with over 2.5 million total artifacts reviewed for private collectors, institutions, and the Government.
