100 dobras coins from São Tomé and Príncipe, or Saint Thomas and Prince Islands, a small nation off the west coast of Africa, are notable their unique designs, numismatic value, and historical significance. The official currency of the nation, the dobra, has undergone several changes over the years and among its coins, 1000 dobras coins stand out due to their commemorative themes and collectible appeal.
The Origin of the Dobra
The dobra (Portuguese pronunciation: [ˈdɔβɾɐ]) was introduced in 1977, replacing the escudo at par and is abbreviated as Db. The currency is divided into 100 cêntimos. The name “dobra” derives from the Portuguese word for “doubloon,” reflecting the nation’s colonial history.
Pegged to the Euro
In 2009, São Tomé and Príncipe signed an agreement with Portugal to peg their currency, the dobras, to the euro. Due to inflation, the dobra was redenominated in 2018, with old 1000 dobras equating to new 1 dobra under the ISO 4217 currency code STN. This stability has helped maintain the value of São Tomé and Príncipe’s currency on the global stage.
History of the 1000 Dobras Coin
Over the years, there have been numerous denominations of Saint Thomas and Prince Islands coins, including the 1000 dobras coin. The first dobra coins were introduced in 1977.
They were minted in denominations ranging from 50 cêntimos to 20 dobras and composed of base metals like most other circulating coins. In 1997, larger denominations, including the 1000 dobras coin, were introduced. These coins often featured wildlife-related themes and were struck in nickel-plated steel or silver. Commemorative versions, such as the 1998 silver holographic issues, highlighted the nation’s natural heritage and technological minting innovations.
The 1998 Holographic Butterfly 1000 Dobras
One of the iconic issues of the 1000 dobras coin is the 1998 silver holographic butterfly coin, a beautiful and intricate piece that combines traditional coin design with modern holographic technology.
Obverse Design
The obverse features a striking holographic image of a butterfly. The hologram creates a dynamic and colorful effect, making the butterfly appear to change colors and move as the coin is tilted. This innovative design reflects São Tomé and Príncipe’s natural heritage and technological artistry.
Reverse Design
The reverse of the coin depicts the coat of arms of São Tomé and Príncipe. This emblem includes a shield with a palm tree and two birds, symbolizing the country’s rich natural heritage. The background often has a frosted finish, providing contrast to the polished elements. Inscriptions on the reverse include:
- “REPÚBLICA DEMOCRÁTICA DE S.TOMÉ E PRÍNCIPE,” translating to “Democratic Republic of São Tomé and Príncipe.”
- The denomination “1000 DOBRAS” and the year “1999,” indicating the coin’s face value and issue date.
The butterfly coin exemplifies the fusion of artistic innovation and cultural representation, making it highly desirable among collectors.
