Your coin DOES have plating, but it's not copper plating.
The switch to copper-coated zinc wasn't made until mid 1982. Before that cents were struck in bronze. That means you have a bronze cent that was plated with a silver-colored metal for use in jewelry or similar. Unfortunately it's an altered coin worth only a penny.
The U.S. Mint did not make a nickel penny in 1977. If you have one it may be a regular penny with a coating or plating of some sort on it. Scratch the rim and see if there is copper underneath.
It's worth maybe 1.5 pence for the copper.
Good Penny - 1977 TV was released on: USA: 1 September 1977
Gold-plated, but not gold. All circulating Eisenhower dollars were struck in copper-nickel, so the gold-plating doesn't add anything to its $1 value.

The last Australian Penny was minted in 1964.
Something like that was done by someone outside the U.S. mint and adds absolutely no numismatic value to it. Being that it's pre-1982, it's worth 2 cents for its copper content.
