The only 14-sided coin issued in Australia annually - and one of few across the world - the Royal Australian Mint's Tetra-decagon Lunar series has always been highly collectable.
For 2019, the series moves to the Year of the Pig and features a grown pig with offspring happily frolicking in the farmyard.
Struck to almost the exact same specifications as the 50c coins we see in our change, there is one obvious difference - there's two extra sides! With 14 sides in all, this tetra-decagon will most certainly never be found in change. A great value collectable, each Australian legal tender coin is housed in red packaging, reminiscent of the traditional lunar red envelope.
