Coins of the Hong Kong dollar

Obverse and reverses of Hong Kong coins – Bauhinia series since 1993

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the beginning of the coin replacement programme in 1993, over 585 million coins featuring Queen Elizabeth II have been withdrawn from circulation.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. The total value of coins in circulation in Hong Kong can be found in Monthly Statistical Bulletin and the Annual Report

Denominations with specifications changed[]

The following current denominations that have changed in size, shape, and or metal content.

Denomination Details
One-cent coin First issued in 1863, the one-cent copper coin had a larger diameter of 27.8mm. The size remained unchanged until 1902 when the coin was reduced in size to 22mm.
Five-cent coin From 1866 to 1933, the five-cent coin was struck in silver. After Hong Kong abandoned the silver standard in 1935, the coin's composition was changed to copper-nickel, and later nickel-brass in 1949 until its final issue in 1988.
Ten-cent coin The ten-cent coin was first issued as a circular coin in 0.800 fineness silver in 1866. The coin's composition was changed to nickel in 1935, and to nickel-brass in 1948. The overall design was changed in 1982, becoming a nickel-brass coin 17.5mm in diameter.
Twenty-cent coin The twenty-cent coin was first issued as a circular coin in 0.800 fineness silver in 1866. The overall design was changed in 1975, becoming a scallop-shaped nickel-brass coin.
Fifty-cent coin First issued by the Hong Kong government from 1866 to 1868, the fifty-cent coin contained 90% silver and had a diameter of 32mm. During the reign of George VI, this denomination was re-introduced, struck in copper-nickel and with a reduced diameter of 23.5mm. In 1977, a nickel-brass coin with a similar design was issued, except for the further reduced diameter.
One-dollar coin The dollar coin experienced three stages of change. First issued from 1866 to 1868, it was minted in 90% silver with a 38mm diameter. The coin was re-introduced in 1960, where copper-nickel coins with a diameter of 29.8mm were issued. The coin was most recently re-sized in 1978, in which the diameter was further reduced to 25.5mm.
Five-dollar coin The 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 1993[]

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.[1]

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.

Security features[]

The $10 coin is made of two metals: a white nickel alloy outer ring and a brass inner core. The standard bauhinia on the obverse gives a sharp embossed image. The neat bonding between the outer and inner rings gives it another unique feature. The $10 coin has an alternate plain and milled edge. The $5 coin has a milled edge. A groove running within the milled edging contains raised English and Chinese characters, which read "Hong Kong Five Dollars". The $1 and 50¢ coins have simple milled edges. The $2 and 20¢ coins have scalloped edges. The 10¢ coin has a plain edge. Under Hong Kong law (sections 98 – 102 of Cap. 200), anyone who makes or possesses or controls or passes any counterfeit note or coin commits an offence and is liable on conviction to imprisonment for up to 14 years.
