50 Sen - Hassanal Bolkiah 1st portrait, w/o numeral 'I' in title

When Brunei's currency authority began issuing coins after the country's full independence in 1984, the Sultan's title on the coinage underwent at least one quiet correction mid-series. This variety lacks the numeral 'I' following the Sultan's title — an engraving omission rather than a deliberate design choice — and was rectified before the series concluded in 1993.
