Freaks and Errors are Missing From Most Collections
Nothing adds prestige to a stamp collection like a rarity, which is why error and freak stamps are so very desirable. Even the most common freak is much scarcer than the normal version of a stamp. And true errors are rare. Some of the most-treasured stamps in the world are error stamps. Now you can have them in your collection!
A Fascinating Philatelic Specialty
Errors and freaks are stamps not prepared according to their design specifications and mistakenly released to the public. Errors are stamps which have mistakes in color, perforation or design. Freaks are stamps which show an inconsistency in their production. There are three groups of stamps listed here: misperforated freaks, imperforate errors and missing color errors.
Misperforated freaks are stamps with perforations falling within the boundaries of the stamp’s design, rather than in the margins, usually caused by simple mechanical problems. With imperforate errors the perforation stage of production is completely omitted. The presence of a single mark from perforating machinery would disqualify it as a true error. This happens rarely and usually involves human error.
