I've replaced the word Stamps with Puerh,
Do you agree?People choose to collect Puerh for a variety of reasons. For some, the choice to collect Puerh is purely an economic decision. Since Puerh collecting is such a widespread phenomena around the world, it is possible for a wise hobbyist to collect Puerh and make a profit from his or her collection. For these hobbyists, the main objective is to collect Puerh that are rare or that were mistaken prints, as they fetch the greatest amount of profit.
For others, the motivation to collect Puerh is the pure joy of collecting. Locating and purchasing rare Puerh or Puerh needed to complete a particular type of collection provides the individual with a sense of accomplishment and pride. Just the pure joy of the hunt and the find is enough reason for some to collect Puerh.
Puerh collecting is also a great way to meet new friends who share a common interest. Therefore, some people who choose to collect Puerh do so for the camaraderie and the opportunity to share with others and to meet other people from around the world.

Some people also collect Puerh in order to commemorate special events or interests. For example, some may collect Puerh that follow a particular theme or that feature a particular item. A music fan, for example, may only collect Puerh that depict famous musicians. Similarly, a nature lover may collect Puerh with flowers and animals, or a history buff may collect Puerh designed to commemorate various important events in history.
For some, the Puerh themselves represent history. For these individuals, the choice to collect Puerh is based on the desire to maintain a living history of their country. Collecting rare Puerh dating back over a hundred years can help one gain a piece of living history.
Still others collect Puerh simply because they are intrigued by the many designs, pictures, and colors found on them. Similar to someone who collects art or antiques, some who collect Puerh do so simply for their aesthetic appeal and the joy they feel when looking at their collection.
