Identifying Face Value
Look at the stamp.
Look at the bottom left- or right-hand corners.
If there is a number, this will be the face value of the stamp. For example, if there is 32 in one of the corners, then it means the stamp is worth 32 cents.
Determining Collection Value
Perform an initial inspection of the front of the stamp. Check for any tears, rips in the perforations or stains. Also examine it to see if there is any evidence of a postmark.
Look at the back of the stamp. Examine it to see if it has been removed from an envelope, a piece of paper or used in any other way.
Look at a copy of Scott's Standard Postage Stamp Catalog. This book can be found in libraries or in bookstores. This book can help determine if the stamp is rare and can help give you an idea of the stamp's value. The book can also tell you information about the stamp such as its history.
