1942 and 1943 Bombay Mint Copper

Anna Fhaumnuaypol During wartime, the demand for pennies and half pennies increased immensely due to pay requirements of Australian and American forces within Australia. However, the availability of metals, especially copper and silver used for coins, was in shortage due to it being used for the war effort for munitions.

While there is a general impression that old coins are too expensive for new collectors to collect that couldn't be further from the truth.

The case for certified coins

Walter Eigner The debate on certified coins vs uncertified coins has been going on in Australia since PCGS first reached the mainstream Australian market back in 2008. While today most Australian coin collectors favour PCGS graded coins, a recent incident has reaffirmed the importance of and buying certified coins and valuing them first, especially when buying on-line.

The Silver of Edward VII

Walter Eigner Although Australia had been a nation since 1901, it wasn't until 1910 that her first official coins were produced. While the Melbourne mint was producing sovereigns and half sovereigns at the time, these were technically Imperial British coins. The first coins issued specifically for Australia were struck in silver and of the denominations threepence, sixpence, shilling, and florin. These featured the Australian Coat of Arms on the reverse and the crowed bust of King Edward VII on the obverse.

Sydney Mint Half Sovereigns

Walter Eigner The discovery of gold in the colony New South Wales in 1851 prompted a surge of immigration among prospectors seeking wealth in the new colony. This lead to the production of half sovereigns in Sydney as of 1855. Only 3.3 million half sovereigns were produced from 1855 to 1869 resulting in individual years being very scarce and valuable.
