"Two up" Pennies are just the same as normal Pennies and are made from bronze. Pennies were used for "Two up" because they are large, heavy and easy to see.
In the event that your Penny has been gold plated, it is worthless as a collectible, as is any modified coin.
The 1944 Australian Penny was minted at one of two mints. Melbourne Mint (no mintmark - 2.45 million minted. Perth Mint (mintmark = Y.) - 27.83 million minted.
The Pennies are probably bronze, and the "Two up" set is available at most Australian Souvenir shops for a few dollars.
The Royal Mint issued no gold Two Pound coins from 1938 to 1952 inclusive.
basically, the zinc electrons in the NaOH solution coat the copper penny and then when you wave it over a Bunsen burner, the two metals form an alloy (a homogeneous mixture with two or more elements) and make brass, not gold.
If you refer to the Australian One and Two Dollar general circulation coins, there is no gold in them, they are made from 92% copper, 6% aluminium, 2% nickel giving them a gold appearance. There are no precious metals in any Australian general circulation coins. Australian non-circulating gold coins which are released annually for investors and collectors, contain 99.99% gold.
All US cents were made in copper not gold. If they were made of gold they would be worth way more than a penny. Your coin is gold plated for decorations or jewelry. It is worth very little. Perhaps a dollar two. If it was not plated gold it wold be worth more.
No. There is no precious metal in any Australian general circulation coin. The Australian One and Two Dollar coins are made from an aluminium-bronze alloy.

The 1922 Australian Penny has no mintmark. Actual mintages were Melbourne - 9,529,440 and Perth - 3,168,000. Identical dies were used so the issuing mint for a particular 1922 Penny cannot be determined.
1 cent. It's plated. If you think about it for, oh, a second or two, would it make sense for the Mint to make pennies out of gold that would be worth $50 or $60, then put them out in change for a penny?
The Australian Two Dollar coin is made from copper, aluminium and nickel and is of a gold appearance. Very occasionally, some Proof coins are made from silver and issued in sets. The 2000 $2 coin was not one of these. If you have a silver $2 coin, it has been plated. Modified coins are worthless as a collectible.
With the exception of cents struck in 1943 and 1944, modern cents were composed of copper zinc and tin. In 1982 it was changed to zinc with a plating of copper.
