Understand Expertized Stamps and Graded Stamps

Like any other collectable, the physical quality and rarity determine the value of stamps. Expertized stamps and graded stamps help to ensure that what you are buying is the original article.

Expertized stamps have been deemed original. The stamp has had no restoration work done on the glue or the printing. Expertized stamps are usually accompanied by a colour picture and a certificate of authenticity.

Despite the usefulness of a unified stamp grading system, it wasn't until 2001 that one was developed. Over the past four years, the system has been upgraded and scrutinized, and its usefulness has become apparent. With a standard stable grading system, it's possible for collectors to buy and sell stamps on an even playing field.

The PSE (Professional Stamp Experts) grading system is based on two main characteristics: soundness and centring.

• Soundness: Soundness determines the overall physical quality of the stamp. It addresses issues like spotting, creases, wrinkles, and tears. A faultless stamp is in perfect condition: no creases, spots, or staining. The rating then degrades through very minor faults, minor faults, fault, major faults, and damaged. Damaged stamps are wrinkled, torn, spotted, creased, or otherwise not in good condition. 

• Centring: Stamps that are well-centred are generally more appealing and sell for more than off-centre stamps. Cutting and perforating the stamps occurs after printing, so it is not uncommon for some stamps to be visibly off centre. However, as technology increased over time, stamps have become consistently more centred, so what is considered a “Fine” rating for an older stamp might be just an average rating for a more modern stamp.

Remember: since eBay does not review stamp listings for authenticity or any other attribute as to quality, it is up to you to research the stamp as well as grading and expertizing issues before you buy.

Learn Stamp Collecting Terms

Learn Stamp Collecting Terms

There are many terms specific to philatelic circles which are especially important when evaluating expertized stamps and graded stamps.

• Crease: A fold in the stamp. They can be rated from faint to heavy and are sometimes pressed or ironed out.

• Fading: Lightened ink from natural causes. 

• Imperforate stamp: Stamps originally sold without perforations. 

• Natural translucency: A condition that is often confused with a thin spot. It is usually ignored. 

• Original gum: A stamp with gum that is in the same condition as it was when applied by the manufacturer. 

• Pin hole: A tiny hole that light can be seen through.

• Previously hinged: The gum on the stamp is original, but it has disturbances that have happened since printing. This could be a sign of tampering, or caused by natural causes. 

• Redistributed original gum: The original gum has been redistributed across the back of the stamp, hoping to hide gum imperfections.

• Regummed: New gum has been added to the stamp. 

• Repair: Any attempt to cover up previous damage to the stamp. 

• Re-perforated stamps: The addition of perforations to defraud collectors. 

• Scrape: A fiber disturbance caused by a surface abrasion. 

• Staining: A discolouration of the stamp’s colour.

• Trimmed perforations: The stamp’s perforations have been trimmed since its issue.
