You have what's called an off-center strike. The error occurs when a coin blank (planchet) doesn't center itself correctly in the collar used to hold the blank while the press strikes the images on the front and back.
The more off-center the coin, the more it's worth, so my guess would be that your coin is worth no more than a couple of dollars. It's still interesting to have as a conversation piece, however.
The value depends on how "off center" it is. A coin that is only slightly off center will be worth around $3-$4 while a coin that is around 80% off center will be worth around $5-$7.
It is worth a penny
Numismedia lists an approximate retail value as of 07/2009 of $250 for a 1972 double-die cent in circulated condition. Uncirculated ones exceed $400.

Please see the many other similar posts on this site for an explanation of how these novelty pieces are made. They do not have any numismatic value, I'm afraid.

It is worth a penny
The last "Wheat Penny" was made in 1958, a cent date 1972 is just a cent.
It is worth face value.
No 1972-S small date varieties are known.
It's worth 2 cents for the copper.
Such a coin does not exist. The last general circulation New Zealand Penny was issued in 1964.
The last Australian Penny was minted in 1964. Their place in the Australian currency was replaced by the 1 cent coin in 1966.

The US NEVER made any gold 1 cent coins
1 cent
That wasn't something done at the mint, rather the cent was likely plated with zinc or nickel. So it has little to no collector value. The US government has never struck a penny in silver.
