The Philatelic Foundation

Founded in 1945 specifically to fill the gap in determining the authenticity of stamps, it was the first expertizing service relying on the most knowledgeable people in the stamp realm. Highly regarded for their expert certificates. They now offer graded certificates similar to those issued by Professional Stamp Experts.
