Any value would depend on the year and condition of the coin. At the very least, it will be worth its gold content at current gold values.
The region of Sovereign Hill, near Ballarat in Victoria, was found to be rich in gold in August 1851.
A Sovereign has a face value of One Pound (GBP). In today's currency, a quarter of a Sovereign would be 25 Pence.
A Double Sovereign is a gold coin of Two Pounds face value. During Queen Victoria's reign, they were only issued in 1887 and 1893 and were minted to a standard 16 grams and 28 mm in diameter.
It is unknown who actually found the first gold at Sovereign Hill. The first gold in Victoria was found in Clunes on 11 June 1851, by James Esmond. However, on 9 August 1851, Victoria's goldrush began tentatively when gold was found at Sovereign Hill near Ballarat, in the same month Victoria gained its independence from the NSW colony.
Your coin is either a Sovereign (22.05mm) or a Half-Sovereign (19.3mm). All Sovereigns and Half-Sovereign coins are made from 22 carat gold.
