1 Sen - Hassanal Bolkiah 1st portrait, magnetic

Historical Context: This 1 Sen coin, issued between 1986 and 1993, represents the early post-independence era of Brunei Darussalam under Sultan Hassanal Bolkiah. Having achieved full sovereignty from the United Kingdom in 1984, Brunei embarked on a period of self-determination, solidifying its national identity and economic prosperity, largely fueled by its vast oil and gas reserves. The coin's issuance during this timeframe underscores the nation's stability and its establishment of an independent monetary system, with the Sultan's effigy symbolizing national leadership and continuity.

Artistry: The obverse features the first portrait of Sultan Hassanal Bolkiah, a dignified and realistic depiction characteristic of modern Commonwealth coinage. While the specific engraver is not publicly documented, the style suggests a collaboration with the Royal Mint or a local artist trained in classical portraiture. The design aims for clear recognition and regal authority, eschewing elaborate ornamentation for a clean, strong presentation. The reverse typically presents the denomination and date, often incorporating national motifs, maintaining a consistent aesthetic with Brunei's established numismatic tradition.

Technical/Grading: Struck on a copper clad steel planchet, this 1 Sen piece weighs 1.74 grams and measures 18 millimeters, distinguishing it as magnetic (KM#15a, Schön#18a). For grading, key high-points on the obverse portrait include the Sultan's hair, forehead, and the highest folds of his uniform. On the reverse, the raised elements of the denomination and date are critical. The clad steel composition, while cost-effective and durable for circulation, can sometimes result in a slightly softer strike compared to solid copper, yet well-preserved examples should exhibit sharp detail.
