This is an aluminium coin issued by the Indonesian government in AD 1957, with a face value of 25 Indonesian sen (hereafter referred to as sen). Although it remains legal tender in theory, persistent historical inflation has rendered the sen obsolete as a subsidiary currency unit, with its only conceivable use being for accounting purposes. Denominations of 50 Indonesian rupiah or lower are exceedingly rare in actual circulation. One hundred sen is equivalent to one rupiah.

The obverse of the coin features the national emblem of Indonesia, commonly known as the Garuda Pancasila. The emblem consists of the Garuda, a mythical golden eagle, bearing a shield on its chest while its talons hold a scroll. The shield is divided into five sections, each symbolising one of the five principles of Pancasila, the foundational ideology of Indonesia. The small pentagonal shield at the centre represents the first principle, “Belief in One Supreme God”; however, President Sukarno interpreted this through a lens of natural theology, allowing for a broader secularist interpretation. The lower-right section contains an interlinked chain composed of nine circular links representing women and eight angular links representing men, symbolising universal humanitarianism. The upper-right section features a banyan tree, signifying Indonesia’s diverse ethnic groups unified under the Republic. The upper-left section depicts a Javanese wild bull (banteng, Bos javanicus), whose social nature symbolises deliberative democracy. The lower-left section showcases rice and cotton, representing the welfare state through agricultural subsistence. The Garuda’s talons clutch a white scroll, though the inscription may be difficult to discern due to wear. It should read “BHINNEKA TUNGGAL IKA”, an Old Javanese phrase meaning “Unity in Diversity”, derived from the 14th-century epic Kakawin Sutasoma of the Majapahit Empire. Surrounding the top edge is the inscription “INDONESIA”, denoting the issuing country and authority. Under Indonesian law, currency denominations of five rupiah or below are issued by the government rather than the central bank.

The reverse of the coin displays the denomination “25 SEN” at the centre, with “INDONESIA” inscribed along the upper edge to indicate the issuing country and authority. The lower edge features the date “1957”, marking the year of issuance. The 1957 minting was the final issuance of the 25-sen coin, and no further subsidiary coins denominated in sen were produced after the 1960s.

The Republic of Indonesia, located in Southeast Asia, is the world’s largest archipelagic state, comprising over ten thousand islands and more than 300 ethnic groups, with territory spanning both Asia and Oceania. Its control over the Strait of Malacca has historically positioned it as a crucial maritime hub linking the Pacific and Indian Oceans. Indonesia declared independence from Dutch colonial rule in AD 1945, with Sukarno, who played a pivotal role in the struggle against Dutch forces, assuming the presidency under a parliamentary democracy. However, due to prolonged political instability, martial law was declared in AD 1957. In AD 1959, Sukarno issued a presidential decree establishing “Guided Democracy”, effectively transitioning to an authoritarian regime until he lost power in AD 1966.

這是一枚印尼政府於公元1957發行，面額25印尼分(以下簡稱分)的鋁幣。雖然理論上至今仍是法定貨幣，但由於歷史上多次的通貨膨脹，分作為輔幣單位已經沒有意義，僅存可能的會計計價用途。50印尼盾及以下的面額，在實際流通中也極為罕見。100分等於1印尼盾。

鋁幣的正面是印尼國徽，通稱為金翅鳥潘查希拉。印尼國徽的主體是金翅鳥(迦樓羅)，胸前佩有盾徽，鷹爪將綬帶展開。盾徽的五個部分各自代表了印尼潘查希拉，即「建國五項原則」。中央的五角星小盾徽，代表第一項原則，「信仰一個至高無上的神」，但蘇卡諾以自然神論加以詮釋，於是可以衍伸為世俗主義。右下部分的橢圓鍊條，其中有代表女性的9個圓環，與代表男性的8個圓環，代表了普世的人道主義。右上部分的榕樹，代表了枝繁葉茂的多元民族，統合在印尼共和國之下。左上部分的爪哇野牛(banteng，或學名Bos javanicus)，以野牛群的社會性來象徵民主協商。左下部分的稻穗與棉花，以生計日用的農作物象徵福利國主義。迦樓羅的鳥爪抓住一個白色綬帶，綬帶上雖因磨損而難以辨識，但應為古爪哇語「BHINNEKA TUNGGAL IKA」，是為印尼國家格言，出自公元14世紀滿者伯夷帝國時期的史詩《卡卡溫·蘇塔索瑪(Kakawin Sutasoma)》，大意為「異中有同」。上方環繞的「INDONESIA」，則標示了發行國與發行單位。按印尼法律，面額5印尼盾以下的貨幣由政府負責發行，而非中央銀行。

鋁幣的背面中央為面額「25 SEN」，即「25分」。上方環繞著「INDONESIA」，標示了發行國與發行單位。下方「1957」為發行年。公元1957年為該25分硬幣最後一次發行，而1960年代後，也從未再發行以分為單位的輔幣。

印度尼西亞共和國位於東南亞，由過萬島嶼及300多個族群組成，領土橫跨亞洲與大洋洲，是世界上最大的群島國家。所控制的馬六甲海峽，自古便是連接太平洋與印度洋的關鍵樞紐。印度尼西亞共和國於公元1945年自荷蘭殖民下獨立，以對荷作戰中有巨大貢獻的蘇卡諾為總統，實行議會民主。公元1957年，由於長期的政治混亂，蘇卡諾宣布戒嚴。公元1959年，蘇卡諾頒布總統令，實行「指導民主」，進行實質上的威權統治，直到公元1966年失去權力。
