The Ghanaian Cedi has been the currency of Ghana since 1965, when it replaced the pre-decimal Ghanaian Pound.
Apart from the regular circulating coinage, the country has also authorised some foreign mints to issue commemorative and bullion coins under its jurisdiction. These are typically in standard ounce-based sizes, such as two troy ounces of silver (abbreviated as 2 oz Ag, where "Ag" comes from the Latin word for silver, Argentum).
This coin is the first issue in the World's Greatest Artists series by Mint XXI, and is dedicated to Leonardo Da Vinci.
Leonardo di ser Piero da Vinci (1452 - 519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor and architect. While his fame initially rested on his achievements as a painter, he also became known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo's genius epitomised the Renaissance humanist ideal, and his collective works compose a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo.
Leonardo is among the greatest painters in the history of art and is often credited as the founder of the High Renaissance. Despite having many lost works and less than 25 attributed major works - including numerous unfinished works - he created some of the most influential paintings in Western art. His magnum opus, the Mona Lisa, is his best known work and often regarded as the world's most famous painting. The Last Supper is the most reproduced religious painting of all time and his Vitruvian Man drawing is also regarded as a cultural icon.
Revered for his technological ingenuity, he conceptualised flying machines, a type of armoured fighting vehicle, concentrated solar power, an adding machine, and the double hull. Relatively few of his designs were constructed or even feasible during his lifetime, as the modern scientific approaches to metallurgy and engineering were only in their infancy during the Renaissance. Some of his smaller inventions, however, entered the world of manufacturing unheralded, such as an automated bobbin winder and a machine for testing the tensile strength of wire. He made substantial discoveries in anatomy, civil engineering, hydrodynamics, geology, optics, and tribology, but he did not publish his findings and they had little to no direct influence on subsequent science.
In the left part of the obverse, the coin depicts the crowned old head of Queen Elizabeth II facing right, wearing the Royal Diamond Diadem crown worn for her Coronation (her effigy known as the "Fifth Portrait"). Normally, the initials of the designer Jody Clark are below the neck truncation when this portrait of the Queen is used on coinage, but they are not displayed here. It is unclear why the Queen's effigy is shown, given that she was Queen of Ghana only until 1960, after which time the country became a republic.
The rest of the surface of the obverse has a background of geometric motifs, central of which is a spiral illustrating Fibonacci's sequence.
Around above is the name of the country, below which the date of issue: REPUBLIC OF GHANA 2019. Vertically on the right, ELIZABETH II. Around below, the face value 10 CEDIS.
Below left and right, separated by the face value, the precious metal content: 2oz Ag 999 (two troy ounces of 99.9% silver).
