a twin island country situated off the northern edge of the South American mainland, lying just 11 kilometres (6.8 miles) off the coast of northeastern Venezuela and 130 kilometres (81 miles) south of Grenada. Bordering the Caribbean to the north, it shares maritime boundaries with Barbados to the northeast, Grenada to the northwest, Guyana to the southeast, and Venezuela to the south and west. The country consists of two main islands, Trinidad and Tobago, and numerous smaller landforms, including Chacachacare, Monos, Huevos, Gaspar Grande (or Gasparee), Little Tobago, and St. Giles Island. Because Trinidad and Tobago lie on the continental shelf of South America, their biological diversity is unlike that of most other Caribbean islands, and has much in common with that of Venezuela.Trinidad and Tobago is the third richest country by GDP (PPP) per capita in the Americas after the United States and Canada. Unlike most of the English-speaking Caribbean, the country's economy is primarily industrial, with an emphasis on petroleum and petrochemicals. The country's wealth is attributed to its large reserves and exploitation of oil and natural gas.
Trinidad and Tobago gained its independence from the United Kingdom on 31 August 1962. Elizabeth II remained head of state as Queen of Trinidad and Tobago. In 1976, the country became a republic within the Commonwealth. Capital: Port of Spain. Largest city: Chaguanas.Currency: Trinidad and Tobago dollar (TTD).
On 14 December 1964, the Central Bank of Trinidad and Tobago introduced notes for $1, $5, $10 & $20. New denominations in the form of $50 & $100 notes were issued on 6 June 1977, although the $50 note was not continued after a shipment was stolen prior to issue. The $50 note was taken out of its brief circulation. The reverses of the current notes feature the Central Bank Building of Trinidad & Tobago. The obverses have the coat of arms in the center, a national bird and a place in Trinidad, such as a market, petroleum refinery, etc. In 2002, new $1 & $20 notes were introduced. In 2003, new $1, $5, $10 & $100 were also introduced. The notes were only slightly changed; they now have more security features & darker colour. Recently, more security features have been added to the notes by the Central Bank of Trinidad and Tobago. In 2012 the $50 note was reintroduced to commemorate Trinidad and Tobago's Golden Jubilee of Independence. On the front of the note is a Red-capped cardinal bird and the commemorative text around the center of the coat of arms. Two versions of this denomination were released, one without the commemorative text around the centre of the coat of arms (general circulation) and one with the commemorative text.
