The fifty-cent coin was first introduced as a .900 purity silver half dollar in 1866.
The design was similar to the British trade dollar, except the image of Britannia was replaced by Queen Victoria.
In 1890, a second issue of this coin was made, this time as a fifty-cent piece.
No more of this denomination was minted until 1951 when a copper-nickel coin was issued.
In 1997 a commemorative coin was issued for the hand over of Hong Kong to China.
