100 Ngultrum Royal Wedding

Issued to mark the October 2011 marriage of King Jigme Khesar Namgyel Wangchuck and Agyem Yangdon Tobjgay, this note was the Royal Monetary Authority's first commemorative banknote — an unusual step for an issuer that had traditionally kept its currency strictly functional. The print run of over twelve million suggests genuine mass circulation was intended rather than a collector-only release, which was not universally the case with royal wedding notes issued by other central banks at the time.

Security specification is modest for the period — watermark and thread only, without the optically variable or color-shifting elements appearing on Bhutan's standard circulation issues by this date.
