It circulates alongside the ten dollar banknote. It was first issued for circulation in 1994 to replace the $10 note, but the coin was not minted after 1997 and the Hong Kong Monetary Authority chose instead to reissue banknotes in 2002. A commemorative issue featuring the Tsing Ma Bridge was released in 1997 for the handover of Hong Kong to China. It was issued in uncirculated and proof sets.^[1] It is Hong Kong's only bi-metallic coin.
