My sister and I found a set of sealed stamps from the West Indies in one of my parent's old books. They'd been there for years and we didn't even know they were there. They're placed on a piece of cardboard with a layer of foam in between. All of it is sealed in clear plastic.
Since some of the edges of the stamps are overlapping one another, it's difficult to determine the years of each stamp. But from what I can tell, they're between 1973 and 1977.
We're just not sure what to do with them. Should we leave them in the sealed packaging or should we remove them?
Also, are there web pages out there where we could find out about the history of those stamps?
Thanks. (Below is a picture of the stamps in question.)
