There are many different methods of postage stamp separation. This article will explain perforations to you.

So what is a stamp cachet? Cachets represent a really fun part of stamp collecting. First of all, though, stamp collectors need to understand what a First Day Cover is (FDC) because cachets are almost always found on them.
Identify different types of stamp grills
Awhile ago in another article, we discussed what a stamp grill is. Now we will help you to identify different types of stamp grills that are known to exist.
First of all, just a quick reminder: stamp makers developed grills in order to prevent the reuse of stamps. The maker embossed the stamp with a special roller. The roller broke up and weakened the fibers in the stamp paper. The cancellation ink could now be absorbed into the paper more. If you tried to wash off the cancellation, the stamp would most likely tear where the grill mark was located because the paper was weaker.

- An abundance (overabundance?) of recognized shades and colours

What is the definition of a stamp plate proof?

What is the definition of a stamp plate proof? I’m often fascinated to see how many different items are considered collectibles in the philatelic world. Not just postage stamps, but souvenir sheets, booklets, first day covers and plate blocks too. Then there’s all the philatelic material that hasn’t necessarily been used for actual mail service: Cinderellas, labels, and SPECIMENs and die proofs. Add to that list plate proofs.
What is a SPECIMEN stamp and should I collect them?
What is a SPECIMEN stamp and should I collect them? Before I answer that question, let’s take a look at page 58 of the 2019 Unitrade specialized catalogue of Canadian stamps.

FAQ-What is a Cinderella stamp?
Defining a Cinderella stamp is a tricky business, as you will see. There always seems to be an exception to the rule in this field of collecting. Cinderella stamps are any kind of adhesive labels that were not issued by a government post office for sending the mail. Here is where it gets complicated though-some stamps that are considered “Cinderellas” were used for the mail, unofficial mail that is. AGGGHHHH!
FAQ-What is a revenue stamp?
Even though they are called “stamps,” revenue stamps have nothing to do with the postal service. They were not used for the sending of the mail. Strictly speaking, they are labels that were applied to official documents. True, they sometimes resemble certain postal issues, but they have no postal value whatsoever. They were issued and used by various governmental offices to collect taxes—hence the name “revenue” stamp.
FAQ-What are BOB stamps?
Many people new to stamp collecting might wonder what BOB stamps are. No, they have nothing to do with your Uncle Bob (sorry, bad joke)! The word BOB is simply an acronym for «Back Of Book». «Which book?» you may ask. The back of your stamp catalogue of course! This article will concentrate on the listings found at the back of your Unitrade Specialized Catalogue of Canadian Stamps. **see note
