A common question in the stamp collecting world is: where can I get my stamp expertly valued? Oftentimes, if an individual wants to sell a rare stamp, a buyer will require a certificate of authenticity. Why? Well, because there have been several instances where a catalogued stamp has turned out to be a fake, or a stamp has been cleverly altered to make it look like something it is not. Who wants to buy a fake? (see article:Fakes and Forgeries-Beware!)
There are many hobbies in this world. Generally, a hobby is undertaken by a person for purposes of relaxation or pleasure, as something to do in their spare time. Personal tastes play a large role in what hobbies a person might adopt; what is interesting for one individual may be boring for another.
One of the questions that I get asked the most as a stamp dealer is «What is my stamp collection worth? ». Obviously, many collectors adopt this hobby simply because it is a passion, but others also hope that their collection may eventually have some re-sale value. How can you tell what your collection is worth?
