50 Ringgit

Pick 50 spans an unusually long production window for a Malaysian issue, covering the tenures of two governors — Zeti Akhtar Aziz, who held office from 2000 to 2016, and Muhammad Ibrahim, who succeeded her. Notes signed by Zeti appear in two distinct signature varieties distinguished by thread width, a detail that trips up collectors who treat them as a single type. The narrow thread variety is the scarcer of the two.

A print run of just over twelve million across a decade is modest for a mid-denomination note in active circulation, suggesting the 50 Ringgit denomination saw relatively light everyday use compared to the 1 and 5 Ringgit notes.
