How to recognize the quality of the new stamp?


To recognize the quality of a new stamp, the factors to be assessed are the following:



The appearance should be cool, "printing fine," as if it had just printed.
The rubber must be original and must not have folds.
Centering must be good. The stamp value changes based on this factor, especially for the stamps before the fifties.
The teeth should not be short
The stamp used must have a clear postmark with the date possibly visible and it does not cover the sticker.
Besides these features, to evaluate the quality of a stamp must also understand in what context it was issued, it is extremely rare or issued in an emergency situation such as to overshadow any defects.
