The vast majority of classic stamps that were issued from 1840 until about 1855-1860 were imperforated. The individual stamps therefore had to be cut out of the sheet with scissors. It was a difficult and time-consuming process, which often destroyed the stamps. Therefore, a new technique was invented. From about 1855 stamp sheets were perforated with small holes, so that the stamps could be separated more easily.
Todays stamp is the Basel Dove Stamp issued in 1845 by the Swiss canton of Basel. This tricolour embossed stamp is considered to be one of the most beautiful of all the classic stamps. CV is 15.000 €
