Jordan ¼ Dinar 1977 - The Silver Jubilee
25th Anniversary of the Accession to The Throne
The coin commemorates the Silver Jubilee (25 years reign) of His Majesty King Hussein bin Talal - the ruler of the Hashemite Kingdom of Jordan. The ceremony took place in 1977 and lasted from May to November. The program had a number of events as the anniversary of the Day of Independence, the Great Arab Revolution, the Arabization of the Jordanian army, the king's accession to the throne and King's birthday.
On the obverse you can see the head of King Hussein in the center of the emblem. The crown symbolizes the monarch system. Wing, on which is placed a crown symbolizes the Hashemite throne.
On the back you can find famous Petra a historic town and archaeological site in southern Jordan. The city is known for its architecture and water pipe system rock. In 1977 there was also the anniversary of the 25 years Nation Bulilding and progress. I believe that is the reason why we see Petra on the reverse.
In 1977 there was another Silver Jubilee - The 25 reign of Queen Elizaberh II.
