1997 before the transfer of sovereignty in hong kong, coins in circulation were all cast with the head of the emperor, which was once the object of collection. Starting from 1993, the government gradually recovered the old coins and replaced them with new ones with bauhinia on the back. However, the Queen's first coin is still legal tender and circulates with the new coin.

The new 10 yuan paper money is purple with blue, which is smaller than the old 10 yuan paper money and adds new anti-counterfeiting measures. The banknotes are signed by Financial Secretary John Tsang and Chief Executive Joseph Yam of HKMA.
