No. Modern Sovereign coinage was first introduced in 1817.
The Sovereign coinage was preceded by Guineas and the spade shield design was not used on any Guinea coinage.
Great Britain's Coinage Act of 1816 determined that the gold Sovereign coin would be the equivalent of 7.98 g of 22K gold. This act occurred due to the need to set a standard and stabilize the nation's currency.
The British Sovereign coinage has been made from 22 carat gold since its reintroduction into the currency in 1817. The Sovereign has a face value of One Pound and was used as currency until the early 20th century when Britain came off the "gold standard", and the Sovereign was replaced with the One Pound note. These days, the Sovereign coinage produced by the Royal Mint is exclusively a collector coin with a price reflecting the value of the gold used to make it.
Other than British gold coins such as the Half-Sovereign, Sovereign, etc., Australia has never produced "Australian" gold coins for general circulation in Australia. The Sovereign coinage minted for Britain were minted to the British pattern from gold mined in Australia and were minted at either of the Melbourne, Perth or Sydney Mints (Mintmarks M, P or S respectively).
Gold was discovered in the Sovereign Hill area of Ballarat in August 1851.
