An accredited appraiser knows that determining the value of a stamp involves much more than just the design itself. Here are some of the factors that affect the value used to determine an accurate appraisal:

    • The age of the stamp
    • Where the stamp was issued
    • How well the design is centered
    • The condition of the stamp gum
    • The perforations on the stamp
    • Whether or not the stamp has been cancelled
    • Rarity
    • Its overall condition
    • How much demand there is for that stamp
