Expertization Service
Overview of Service
The Vincent Graves Greene Foundation will provide expertizing services related the authenticity and condition, unaltered or otherwise of British North American stamps and historic postal items. Learn more about what’s involved in the expertizing and certification process.
The fee for this service is based on the assumed value of the item in question. Values of stamps and covers are to be based on current editions of Scott or Unitrade catalogue. Unitrade values are to be based on unused or used stamps in fine condition without extras.
The Greene Foundation issues a genuine certificate, green colour, where the stamp or cover is genuine and it is either fault free or has faults such as a tear, thinned paper, disturbed original gum, missing perforations, or other faults which have not been repaired.
Where a stamp on or off cover has faults which, in the opinion of the Expert Committee, have been repaired with the intention of deceiving a collector, then these alterations are described and a pink certificate declaring a lack of genuineness, is issued. Such repairs include removal of a cancel, regumming, repair of tear, addition of margins, rebacking a stamp, alteration of the issued colour, and addition of a stamp to a cover on which it did not originate.
