Prague Astronomical Clock, which is annually admired by millions of tourists from all over the world, is one of the greatest monuments of old Prague. Therefore, the Czech Mint pays it homage by issuance of a large gold coin whose weight is derived from the historical forty ducats.

The story of the instrument, which measures not only time but also the position of celestial bodies, began in 1410. Therefore, the Prague Astronomical Clock is one of the oldest in the world. It shows the technical skills of medieval watchmakers and a unique work of art that combines many different styles - from Gothic to Romantic. The Prague Astronomical Clock is also surrounded by a number of legends that say that its function is connected with the very existence of our homeland. When the painter Josef Mánes received a contract for the creation of the astronomical clock plate to complement the astronomical dial of Mikuláš of Kadaň, his colleagues tried to discourage him. According to the prophecy, madness awaited everyone who worked on the astronomical clock. However, the disaster was not only a threat to the artist himself - the astronomical clock had not worked for centuries, and if it had been re-launched, the Czech lands would have been hit by a disaster. Mr. Manes ignored the warning and created a monumental allegory of twelve months. Whether it was a coincidence or a real curse, the prophecy came true - the astronomical clock was finally put into operation in 1866, when the Prussians invaded Bohemia, the cholera epidemic started and the painter suffered from mental illness…

The reverse side of the coin was processed by medal maker Petra Brodská, DiS. It is dominated by a view of the south side of the Old Town Hall´s tower, supplemented with elaborated details of the astronomical clock and its calendar plate. The reverse side bears the inscription PRAGUE ASTRONOMICAL CLOCK. Since the coins are issued in a foreign license of the island of Niue, the obverse side bears the necessary attributes of the issuer. The attributes are the name and the portrait of Queen Elizabeth II, the nominal value of 250 DOLLARS (NZD) and the year of the issue 2020.

The limited schedule of issuance counts only 99 pieces. Issue follows the previous 40-ducat with the motif of the Infant Jesus of Prague.
