The first Seborgan stamp, with a value of 1 luigino, was issued in 1994.
In the following year, this first issue was followed by other issues called “HSH Giorgio I and Coats of Arms of the Principality”, “Coats of Arms of the Principality of Seborga in history”, “Coins of the Principality of Seborga – Year 1995”, “Grand Masters of the Cistercian Knighthood”. On 23 July 1995 a commemorative stamp of half luigino was issued on the occasion of the “1st Football Trophy of the Principality of Seborga”. Another 1 luigino stamp was also issued on 28 December 1995.
The stamps were made on behalf of the Principality of Seborga by “Erinnofila Anfe” of Trezzano sul Naviglio (MI).
As Prince Marcello I ascended the throne, an issue was made on 20 August 2014, consisting of two philatelic sheets: one depicts some luigini from the series of Prince Giorgio I and Prince Marcello I, while the other depicts the coat of arms of the Principality, the official portrait of Prince Marcello I and some glimpses of Seborga.
On 20 August 2022 HSH Princess Nina presented the first stamp issue of her reign. The subjects were chosen by the Crown Council following a specific competition held between March and May of the same year.
The issue consists of 3 philatelic leaflets:
- the first sheet includes 6 horizontal stamps by different authors (Antonio Barelli, Alessandro Andrea Pitzoi Arcadu, Fernando De Paolis, Club 500 Monte-Carlo); it features two pastel drawings that reproduce two views of Piazza della Libertà, a computer-graphic drawing representing the Princess of Seborga, two Templar-themed compositions and a composition showing a view of Seborga with a nice Fiat 500 and the profile of the Princess;
- the second leaflet includes 9 vertical stamps by the author Fabrizio Annovi, who is specialized in creating fantasy designs for coins and stamps; they represent the flag and the coat of arms of the Principality, the Princess, the luigini, the guards and glimpses of our country;
- the third leaflet consists of 9 horizontal stamps by the author Gian Paolo Terrone representing the flora, fauna and food typical of our area: pesto, black tomato, Taggiasco oil; bee, wild rabbit and boar; mimosa, broom and olive tree.
The stamps are worth 20 cents of luigino each and were printed in the United States.
