New Discovery!-Post and Go stamp security overprint missing!
Whilst looking through some ‘Hytech’ vended Post and Go Stamps I have come across some where the security overprint does not cover the whole of the stamp~there is a discernible and noticable gap at the base of the stamp where the print does not reach the bottom of the stamp. Upon checking with other dealers they have noticed the same on a handful of stamps purchased at Spring Stampex 2011 and have confirmed that at least one whole strip of five with this error on each stamp exists.
