Value of a stamp VS same stamp on a cover. I think it might be useful to know.
I refere to the following topic :
Quote:
#23 earlier than the ERD suggested in the Unitrade
I called to a well known stamp store in Montreal "CITY STAMP MONTREAL" for a rendez-vous as to get an expertise on the real color of the stamp and what's next for the ERD and the value
At the phone, whitout having seen the stamp, I was told that if the stamp was a real #23 with an ERD earlier than the one given in the litterature, a correction would be made and the stamp value in the catalogue would remain about the same.
Of course, if the stamp is presented on an auction, it might be sold at a hire value depending on how hard a collector wants the stamp.
On the other hand, if the stamp revealed to be #23 and was stick on a cover, the value would have raised up to $3,000 to $4,000 just like that!
What a world stamps collecting
