To properly price stamps you need to consult a catalog. Some libraries have copies of you can use, otherwise you'll need to purchase them.
Depending upon what country you are interested in, you can purchase a specialized catalog that deals with just that country. You'll find tweezers and a magnifying glass handy as well.
Many people use Scott's Catalogs. If you are interested in Canadian stamps you should look for the Unitrade Specialised Catalog of Canadian Stamps. They use the Scott's numbering system so it's easy to use.
Other catalogs include Stanley Gibbons and Michel. Depends upon your preferences.
The price will depend on the edition of the stamps and the condition of the cover.
First Day Covers are worth more than ordinary covers. Stamps bought on the first day themselves, without cancellations, cannot be identified as being issued on the first day. Leave them on the cover if you have them!
There is no such thing as a first edition stamp. First Day of Issue are stamps canceled on the first day that a stamp is available for sale to the public. Older stamps, over 70 years or so, on first day covers have good value. Most current ones can be purchased for about a $1.
