Stamp Grades and Their Importance to Stamp Values


If you're serious about stamp collecting and want to have the best stamp collection that you can, be aware that the most important factor in any stamp's value is its grade.

Stamp grading is determined by a variety of factors, but those factors do not include a stamp's subject matter, rarity or age. To the contrary, a stamp's grade is determined by how its design is centered between its perforations or, if it's an imperforate stamp, its margins. Both horizontal centering and vertical centering are taken into account. Grade also refers to the condition of the stamp's gum (if it's a mint stamp) or how the cancellation of a used stamp affects its design.

Grading stamps takes some experience - looking at a lot of stamps in a variety of different grades. After you've looked at just a few stamps you may be able to distinguish between stamps with a high grade and those with a low grade. Given enough time and experience, you'll begin to be able to tell differences in grading in most stamps.

Stamp grades are somewhat standardized, ranging from superb at the high end, to poor at the low. If you are going to become a serious stamp collector and invest some serious money, it's crucial when buying a stamp to know what grade of a stamp you are getting. The better the grade of stamps in your collection, the better and more valuable your collection will be.
