Coins of the Hong Kong dollar


The Hong Kong coinage, including 10¢, 20¢, 50¢, $1, $2, $5 & $10, is issued by Hong Kong Monetary Authority on behalf of the Government of Hong Kong. From 1863 until 1992 these coins were embossed with the reigning British monarch's effigy. From January 1993 to November 1994, a new series depicting the bauhinia flower was gradually issued, including a new denomination of $10. Since the beginning of the coin replacement programme in 1993, over 585 million coins featuring Queen Elizabeth II have been withdrawn from circulation. However, these coins remain legal tender.

One-dollar coinThe dollar coin experienced three stages of change. First issued in 1866, it was minted in 90% silver with 38mm diameter. Subsequent changes were made in 1960, where copper-nickel coins with a diameter of 29.8mm were issued. The latest design was issued in 1978 where the diameter was further reduced to 25.5mm.
Five-dollar coinThe first series of decagon shaped five-dollar coin was issued in 1976. Yet, as it was easily counterfeited during that era, the colonial government decided to change the design of the five-dollar coin to a circle-shaped design with security edge starting 1980.

Coins in circulation since 1997

Since the introduction of Octopus card in 1997, small value payments and purchases in Hong Kong are mostly done as Octopus transactions. The Hong Kong Monetary Authority from 1998 to 2011, stopped issuing new coinage as the territory had stored enough for use. In 2012, the Hong Kong Monetary Authority resumed the minting of coins of the Bauhinia series after 14 years of non-minting of circulating coins, due in part of increased consumption for coins since 2004 in the territory.
The obverse of each newest coin bears the standard bauhinia, with the word "Hong Kong" in Chinese characters and English. The reverse features the denomination in Chinese characters and English with a large Arabic numeral in the centre and the year of issue below.
