Additional information

Historical Context: Issued in 1952, this 1 Sen coin marks a critical period in Indonesia's history, mere years after achieving full independence from Dutch colonial rule in 1949. Under President Sukarno, the young Republic established its national identity and economic sovereignty. The introduction of its own currency, with the Rupiah and its Sen subdivision, was a tangible assertion of this newfound independence. As a low denomination, the 1 Sen was crucial for daily transactions, reflecting nation-building practicalities.

Artistry: The 1952 1 Sen design reflects a utilitarian yet clear aesthetic, typical of early post-colonial coinage. While no specific engraver is credited, the design likely originated from the Indonesian Mint's department. The stylistic approach prioritizes legibility and national identity. The obverse displays "REPUBLIK INDONESIA" and the year 1952 in a straightforward typeface. The reverse features the large numeral "1" above "SEN," ensuring immediate value recognition. This minimalist design underscores its functional role.

Technical/Grading: Struck in lightweight aluminium, 18 mm in diameter and weighing 0.75 grams, the 1952 1 Sen is susceptible to handling marks and surface abrasions due to its softness. Key high-points for grading include the raised lettering of "REPUBLIK INDONESIA" on the obverse and the numeral "1" on the reverse. A fully struck example exhibits sharp, distinct letters and clear field-device separation. Planchet quality varies; examples free of significant nicks, dents, or weak strikes are highly sought after.
