The dobra is the currency of São Tomé and Príncipe. It is abbreviated Db and is divided into 100 cêntimos, although inflation has rendered the cêntimo obsolete. The dobra was introduced in 1977, replacing the escudo at par.
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. In 1997, larger denominations were introduced of 100, 250, 500, 1000 and 2000 dobras. Of these, the 100 and 250 dobras are round, the remaining are equilaterally curved heptagonal. All circulating coins bear the country's coat of arms on the obverse, with the text "Aumentemos a Produção" on the reverse.
Banknotes
In 1977, notes were introduced for 50, 100, 500 and 1000 dobras by the Banco Nacional de São Tomé e Príncipe.

A new issue was issued in 2006 with upgraded security features. All notes bear the portrait of Rei Amador on the obverse.
