The Siegel Census

In the course of our research and catalogue production we have compiled comprehensive census information on many of the rarest United States and Worldwide stamps. This section of our website illustrates every known example of well over 100 of the greatest rare stamps. We also maintain records on scores of others that are not published here at our website.

There are many United States stamps that look similar to the rarities listed below. Some of the differences between expensive rarities and common stamps can be subtle, including differences in perforation, shade and size. These stamps should have certificates from a recognized expertizing committee, such as The Philatelic Foundation or Professional Stamp Experts.
