Front: Yusof bin Ishak, Singapore's first President, engraved in red with the collar of his shirt cut sharp against the guilloche — the portrait that gives this whole family of notes its name. The country is named in all four official languages across the top: Singapura, 新加坡, சிங்கப்பூர், Singapore. At left, the state coat of arms with its lion and tiger and the motto Majulah Singapura sits in a clear window; two raised dots at the top right mark the value by touch.
Back: A sports tableau: a woman running, a badminton player reaching for a smash, a footballer striking the ball, and behind them a sailor hard over in a dinghy and a swimmer mid-stroke through the spray. The theme is spelled out simply — SPORTS — in small capitals at the lower left. A stylised lion's head, Singapore's national symbol, sits beside the numeral 10, whose zero is drawn as a football.
The Portrait Series arrived in 1999 to replace the Ship Series, and the ten dollars moved from paper to polymer in 2004 — this is that polymer note. It remains legal tender and in everyday circulation, still the workhorse denomination alongside the two and fifty dollar notes.
