A treasure trove* of more than 5600 Australian coins, some of them dating back as far as the 1800s, has been uncovered on a Toowoomba construction site in Queensland.

The historic find was made two years ago when a former employee working on the site stumbled across the coins buried in a metal container. However, news of the find could not be revealed until this week after a Department of Environment and Science investigation into the find had finally finished.

The coins are in Australian currency, including a 1927 silver florin.

Florins were a coin used in Australia before decimalisation* in 1966. Between 1910 and 1945 they were made from 92.5 per cent silver and 7.5 per cent copper.

A DES spokesman said further investigation showed all the coins were of archaeological* significance, varying from copper to silver, with a date range from 1882 to 1940.

“While the financial value of the coins is unknown, the historical value and importance is high,” the spokesman said.

Investigations into who buried the coins, and why, are ongoing.

The treasure finder was fined $1828 for failing to follow the Queensland Heritage Act, which states a person who discovers any archaeological artefact* that is an important source of information about an aspect of Queensland’s history must notify the DES as soon as possible after making the discovery.

The coins are now being kept in a secure location while it’s decided where to house them permanently.

Before 1770: The First Australians did not use money, they used a barter system, which means trading goods (for example, trading chickens for wood).

1778: The British sent the First Fleet to Australia to set up a convict* colony, but they didn’t send much money because the convicts were not paid and the soldiers were supplied with goods for free. Most of the first coins used in Australia came from the pockets of the officers, sailors and convicts who settled in Australia. These coins included English sovereigns, shillings and pence; Spanish reales; Indian rupees and Dutch guilders.

1800: As the Australian population grew, a proper money system was needed. Governor King tried to solve the problem by fixing the value of all of the different coins in the colony. These became known as the Proclamation Coins*. However, there was still not enough money to go around.

1813: The British Government decided to send 40,000 Spanish dollars to the colony. Governor Macquarie asked a convict named William Henshall to punch a round piece out of each of the Spanish dollars. This almost doubled the number of coins – producing 39,910 donut-shaped pieces known as ‘holey dollars’, and the same in solid pieces called ‘dumps’.

All the coins were stamped with the words New South Wales, and were used in NSW until 1829 and in Tasmania until 1849.

1825: The English Parliament passed the Stirling Silver Money Act, which officially made British coins the only recognised form of currency in Australia. Silver coins were shipped to Australia after being made at the British Royal Mint.

1855: A branch of the British Royal Mint was opened in Sydney. A Melbourne branch followed in 1872 and a Perth branch opened in 1899.

1910: The first distinctive* Australian coins were made. The coins were based on the British

sterling system of pounds, shillings and pence.

1965: The Royal Australian Mint opened in Canberra meaning Australia now had its own Mint.

1966: On 14 February, decimal currency was introduced in Australia, with 1c, 2c, 5c, 10c, 20c and 50c coins, which were all round in shape.

1969: The circular 50c coin was replaced by a 12-sided 50c coin which we still use today.

1984: $1 coin introduced to replace the $1 note (which was made out of paper).

1988: $2 coin was introduced to replace the $2 note.

1992: Australia’s 1c and 2c coins were taken out of circulation because their

worth had dropped, and they were becoming too expensive to make.
