This sterling silver ingot depicts Hajjah Fatimah Mosque, one of the first places of worship to be designated a National Monument. This is part of a set of ingots struck by the Singapore Mint in 1978. As a complete set, the ingots depict five of Singapore's oldest places of worship: Thian Hock Keng Temple, Sri Mariamman Temple, Armenian Church, Hajjah Fatimah Mosque, and St. Andrew's Cathedral. A maximum of 3,000 pieces of each design were issued by the Mint, which agreed to make a donation to the Preservation of Monuments Fund from the proceeds of the sales. The sale of these ingots was announced on 20 Oct 1978, and by 26 November the same year all five of the design were fully subscribed. Hajjah Fatimah Mosque was built in 1846. Originally called the Java Road Mosque, it was later named after the woman who established the mosque, Hajjah Fatima, who was a wealthy businesswoman who ran a trading post in the early 19th century. The mosque was gazetted a National Monument on 28 June 1973, part of the first group of 8 buildings to be designated as such.
