About PSE

The PSE Advantage

PSE offers many advantages to all serious collectors who need authentication and grading services for United States, U.S. Possessions, Confederate States of America, stamps, covers, postal stationery, and Back-of-Book material.

The PSE Authentication Process

PSE has a well-deserved reputation in the philatelic community for honesty and integrity in all of its dealings. No other stamp authentication company holds itself to a higher ethical standard than PSE.

Our philatelic experts are forbidden from rendering an opinion on any item in which they may have an interest, whether financial or otherwise. Strictly enforced policies and procedures are in force to prevent this from happening.

Total anonymity is practiced throughout the authentication process. Once received, each item is assigned a PSE Control Number, which is an item's only identification as it makes its way through the authentication process. No information is divulged to anyone at any time regarding the ownership of a submission, whether past, present or future.

From Magnifiers to Video Imaging Technology

PSE employs an impressive array of philatelic examining equipment, from magnifiers and millimeter gauges to state-of-the-art technology. Our portable Forensic Foster & Freeman VSC-4c color-infrared-UV video imaging system enables us to detect even the most subtle forgeries, alterations, erasures, and masked defects. It can be used to display items side-by-side or overlaid on known authentic stamps for comparison.
