Forgeries have been around since the earliest days of stamps. There are two principal categories of forgery; those designed to defraud the postal authorities, and those meant to defraud the collector. Forgeries in the former category are often desirable and valuable, while those intended to defraud the collector - except for some 'classics' - are not. The internet is plagued by forgeries. All stamps offered on the Stanley Gibbons website have been vetted by our experts, and bear a lifetime guarantee of authenticity for your peace of mind.
