The Value of Error Stamps

Error stamps could be detected either through out visual inspection or use tools like a magnifying glass or scanner, indeed. In philately, a famous terminology prior to classify of the error stamps is so-called EFO – Errors, Freaks and Oddities, a term referring to all kinds of things that goes wrong when producing stamps. It's encompasses the whole major designs of error stamps and printing with poor quality or mistake. Stamps that have major uncertainty in comparison with the acceptance quality could be considered as errors, it's caused during printing process which do not show the intended appearance of the desired design or having abnormality.

Major Errors that something would be seen easily or clearly without referring to the acceptance quality or display strange features in comparison with the catalogues. The classic examples were missing denominations, centre inverted, colour shades, centring offset, double impression, mis-perforation and others. Used stamps with major errors could be valuables and rare.
