Trentino, today a province in northern Italy, was a part of the Austrian Empire in 1918 when Italian forces occupied it during World War I and began using new postage stamps.
The first stamps used by the Italian occupiers were Austrian issues with new overprints reading ‘Regno d Italia / Trentino / 3 nov 1918‘. Eventually, Italian stamps with the overprint ‘Venezia / Tridentina‘ and a surcharge were issued, and finally, in 1919, Italian stamps with a surcharge and the phrase ‘di corona‘ were used (as in Venezia Giulia, a nearby area also occupied by Italy).
Trentino (called Trento in Italian) stamps from this era are highly collectible, if not as ubiquitous as other Italian and Austrian stamps, and often not too expensive. Browse the current Trentino Italian occupation of World War I stamps for sale in this section, which is updated daily.
