Many factors are crucial for a good stamp collection: for example, it depends on the skill of the collector, the time he invests, the collecting area he develops and, of course, the financial budget that is available.
A good collection primarily consists of the highest quality brands. What counts is the top quality of each individual brand. A good philatelic collection almost always includes an interesting, unusual collecting area that differs significantly from other collecting areas and collections.
Of course, a certain degree of completeness is also important.
"A good collector enjoys stamp collecting three times: firstly when purchasing them, secondly when owning them and thirdly when selling their collection."
