Why should I send my stamps and covers to the PF for expertization?

The value of a stamp or cover is based on not only its rarity, but also its condition. Fake cancels and non-contemporary markings can significantly lower its value. With the unmatched PF reference library and an expertise built over many decades of philatelic research, our expert staff and broad range of outside consultants will give you the highest level of confidence in the genuineness and condition of your material.
