São Tomé and Príncipe Banknotes: A History of the Dobra
The currency of São Tomé and Príncipe, the dobra, has undergone significant transformations since its formal introduction. Managed by the Banco Nacional de São Tomé e Príncipe, the nation's banknotes reflect both the economic challenges of inflation and the rich natural heritage of the islands.
The First Dobra Era
The first series of dobra banknotes was introduced on September 30, 1977. Initially, the currency was issued in denominations of 50, 100, 500, and 1,000 dobras. As the economy evolved, the central bank expanded these offerings in 1996 by introducing higher denominations of 5,000, 10,000, 20,000, and 50,000 dobras. By 1997, the lowest denomination notes from the original series were phased out and replaced by coins.
To combat counterfeiting, a new issue featuring upgraded security features was released in 2006. However, continuous inflation eventually necessitated the introduction of the 100,000 dobras note in December 2008, a denomination that was widely accepted by the general public.
Visually, most notes from this era featured the portrait of Rei Amador on the obverse (the front side). The exception was the 100,000 dobras note, which instead featured the portrait of Francisco José Tenreiro.
[ไม่มีภาพประกอบ]The Second Dobra and Redenomination
In 2018, São Tomé and Príncipe implemented a redenomination—the process of changing the face value of a currency to make transactions simpler. This led to the issuance of a new set of banknotes in denominations of 5, 10, 20, 50, 100, and 200 dobras.
This new series shifted its artistic focus toward the islands' biodiversity. The obverse of these notes features various species of butterflies, while the reverses depict local wildlife. Initially, the 5 and 10 dobra notes were printed using polymer, a durable plastic material designed to last longer than traditional paper.
However, the tropical environment of São Tomé and Príncipe proved challenging for these materials. In 2020, the Central Bank issued a new version of the 200 dobras note to replace a previous version that suffered from poor paper quality. Simultaneously, the bank decided to revert the 5 and 10 dobra notes from polymer back to paper, as the plastic versions were found to be unsuitable for the local climate.
