Hello, William Weiss here. I am an author of several books on various postal history subjects and I am also a noted successful exhibitor having won numerous awards.

I am certified expert and currently serve both the American Philatelic Society (APEX) and the Professional Stamp Experts (PSE) committees. Life Member of APS #48798 (40+ years).

With Over 50 Years of Collecting Experience and Intense Philatelic Study of U.S. Issues from The Classics Through Moderns, I Can Offer A Qualified, Professional Evaluation and Authentication of Your Investments.

All mainstream philatelic public auction firms, and most top retail dealers allow buyers to place purchases "on extension" for certification. Unfortunately, not all sellers on eBay allow certification. Therefore, to buy expensive stamps from such sellers is a big gamble.

If you have any questions regarding my expertizing service contact me here.
