Many stamp collectors observe the price value of special stamps and limited edition stamps. They take it as an important source for their investment and profit. Specialized collectors limit their interests on searching only the stamps that they may think have great values and price. A normal collector does not mind whether his collections are special or average. On the other hand, specialized collectors consider stamp collecting as a source for investment and income.

Another avenue for collections is the postal stationery. It is a small piece of postal paper, envelope size that has a postal card and a letter sheet on it. Some also prefer the government-released postcards also known as the aerogram stamps. These are letters, which are sent through airmail.

The souvenir pages are also interesting to collectors because these are pre-cancelled stamps from the brochure page of ceremonies or occasions that contains all the issuing subscriptions, design, and printing. They may have similar features with the first day ceremony postage stamps.
