What is STN currency？
The dobra (Portuguese pronunciation: [ˈdɔbɾɐ]) is the currency of São Tomé and Príncipe. It is abbreviated Db and is divided into 100 cêntimos. The first dobra (STD) was introduced in 1977, replacing the escudo at par. Due to past inflation, on 1 January 2018 the dobra was redenominated at a rate of 1000 to 1, and given the new ISO 4217 currency code STN.
São Tomé and Príncipe signed a deal with Portugal in 2009, linking the dobra with the euro. The exchange rate was fixed at 1 EUR = 24,500 STD on 1 January 2010, which means that the new dobra is pegged to the euro at €1 = 24.5 STN / nDb.
The name derives from Portuguese dobra, meaning “doubloon.”
STN Coins
In 1977, coins were introduced for 50 cêntimos, 1, 2, 5, 10 and 20 dobras. Except for the brass 50 cêntimos and 1 dobra, these coins were struck in cupro-nickel, as was the 50 dobras introduced in 1990. These coins depicted a combination of food produce and local flora and fauna. These coins, although seldom seen in circulation today due to chronic inflation have never been demonetized and can still be used as tender.
In 1997, a new coin series with larger denominations was introduced consisting of 100, 250, 500, 1000 and 2000 dobras. Of these, the 100 and 250 dobras are round, the larger of the three are equilaterally curved heptagonal. These coins were all struck in nickel-plated steel and depict wildlife-related themes.
All circulating coins bear the country’s coat of arms on the obverse, with the text “Aumentemos a Produção” and the valuation on the reverse.
With the redenomination of the dobra in 2018, coins were introduced in denominations of 10, 20, and 50 cêntimos and one and two dobras.
STN Banknotes
On 30 September 1977, notes were introduced for 50, 100, 500 and 1000 dobras by the Banco Nacional de São Tomé e Príncipe. In 1996, 5000, 10,000, 20,000 and 50,000 dobras notes were introduced, with the lowest denomination notes from the previous series being replaced by coins in 1997. A new issue was released in 2006 with upgraded security features.
In December 2008, the 100,000 dobras note was introduced as continuous inflation deemed the new denomination necessary. The note has been very well received and accepted by the general public.
All notes bear the portrait of Rei Amador on the obverse, however, on the 100,000 dobras note is the printed portrait of Francisco José Tenreiro.
Banknotes of five, 10, 20, 50, 100, and 200 dobras were issued in 2018 with the redenomination of the dobra. The five and 10 dobra notes are printed in polymer, and all the banknotes feature various species of butterfly on the obverse with local wildlife depicted on the reverses.
In 2020, the Central Bank of São Tomé and Príncipe issued a new version of the 200 dobras banknote, to replace the previous version caused by the poor quality of the paper used to print the note, and 5 and 10 dobras banknotes, reverting to paper, as the polymer versions of the two denominations were unsuitable due to the tropical environment of São Tomé and Príncipe.
