This is a full set of Pa'anga banknotes released on the 29.6.2015. This is a new serial with the new portrait of the current King Tupou Vl. These notes were released to coincide with the coronation of the King on 4.7.2015. Unlike the 2009 series, this series only come with 6 notes, without the One Pa'anga piece. I can only assumed that the One Pa'anga has been replaced by a coin. The designs of these notes are similar to the 2009 issues, except that the reverse design of the two Pa'anga has been replaced by the previous design of the one Pa'anga. In addition to this, the designs also slightly changed with raised prints on the title Kingdom of Tonga, the value and the signatures, and with shiny threads on the 2, 5 10 and 20 Pa'anga notes, watermark of the new King Tupou Vl and the denomination value on the back of each note is also smaller comparing to previous issues. Like the 100 Pa'anga, the 50 Pa'anga is also a Hybrid note. All notes printed with 3 signatures - Prime Minister (Samiuela Akilisi Pohiva), Minister of Finance (Aisake Valu Eke) and Bank Governor (Dr Ngongo Kiao). I personally believe that this whole set could be Hybrid notes. The texture on the notes are very difference from previous issues. It has a more glossy look on the surface and the notes for the lower denominations feel a bid thicker and heavier too. This is just my opinion. You can also basically considered this issue as Commemorative notes to celebrate the coronation of the country's King.
