No Australian general circulation coin has ever been minted with a hole in it.
During the Second World War, Australia produced some coins for use in the Internment Camps. These coins will have "Internment Camps" inscribed on them.
The Australian Colonies were suffering from a shortage of coinage since England was unable to keep the Colonies supplied during the early 19th century. To resolve the problem, Governor Lachlan Macquarie acquired some 40,000 Spanish Dollars in 1812. These coin had their centres punched out to make them unusable in any other country.
They became known as the "Holey Dollar" and "Dump", the "dump" being the centre that was punched out. The "Holey Dollar" had a face value of 5 Shillings and the Dump, a face value of Fifteen Pence.
Although these coins were not Australian Coins and they were not minted with a hole in them, they are amongst the most famous of Australian and were used until 1829 in the Australian Colonies.
If you refer to the collector value of 1954 Australian coins, not much. Any value would be dependent on the condition of the coins.
Silvery coloured Australian coins in general circulation are the 5, 10, 20 and 50 cent coins. Their composition is 75% copper and 25% nickel. There is no silver in any circulating Australian coin.

The Royal Australian Mint (RAM) uses a variety of "fonts" on Australian coins, but the information is confidential so as not to make it any easier for counterfeiters.
Although the Australian one and two cents coins were withdrawn in 1992, they are still considered to be legal tender. Any Australian bank should accept them as a deposit into your account or, exchange them for coins of an equivalent value.
The first exclusively Australian coins were issued for circulation in 1910. Any coins circulated in Australia prior to 1910 were British coins. Occasionally there were coins from other countries suitably restruck for circulation in Australia.
No. The only Australian decimal coin to ever contain any silver, was the 1966 round 50 cent coin. They were withdrawn from circulation when the price of silver skyrocketed in 1967.
Australia does not produce any Sovereign coins.
I cannot find any reference to an Australian gold coin from any year with an eagle on it. Do you have any further information?
No Australian Penny has ever been minted in gold, they were made from bronze. If you have a gold Penny, it will be because somebody has gold plated it, perhaps to commemorate or celebrate a significant event for somebody. Modified coins have no collector value.
From 1967 onwards, no general circulation Australian coin has contained any silver, or any other precious metal at all. Since 1967, all Australian "silver" coins are made from a 75% copper and 25% nickel alloy.
All Australian coins minted since the first post-Federation Australian coins were minted in 1910, are still considered to be Legal Tender according to the Australian Currency Act. You may however, have a problem getting a shop keeper to accept a handful of Pennies and Shillings as payment, not only because the shop keeper possibly will not want them, but there seems to be a grey area in the interpretation of the Act as to what constitutes Legal Tender. As of 2010, the only Australian coins to have been demonetised are the early Proclamation coins and the Holey Dollars and dumps.
