Hello, I have had these for years never thought much about them but recently trying to figure out what I have here. I have about 40 different envelopes containing mint 1937 British Empire Coronation stamps. I have looked at E-bay and see there are some like this listed for sale. The complete sets having the highest value. I may be missing a few but have the rare ones. (Hong Kong and others) The stamps are in flawless condition having spent their days in the envelopes, a couple of envelopes are damaged. I was wondering about the Kresge envelopes would they add to the value of this set or not? Thanks for any help.
