Preguntas Frecuentes
What is better: mint or used stamps?
Generally mint stamps are more valuable. Hinged mint typically less than never-hinged (NH).

Perfect centering adds premium. Off-center stamps can be worth 50% less than well-centered examples.
Are damaged stamps worthless?
Not always. Rare damaged stamps can still have value, though much less than undamaged versions.
