None.
The US doesn't make gold-plated coins. Anything you find was made by a private company that plated ordinary US Coins and sold them as "special collectibles". However these items are rarely worth what they sell for.
None of the Bicentennial coins were struck in gold. Many of these coins have been gold plated privately and sold as "Collectibles" but they have no numismatic value. It's just a dollar.
It is impossible to say what a copy coin is worth. Copy coins have no collector value, their only value comes from what the coin is made with. Some high end copies are made out of the same material that the authentic coin is made out of, in this case, it would be gold. Others might be gold plated silver, still others may be gold plated copper, or you might have gold plated steel or lead. Without seeing the coin in person it is impossible to say because there are so many types of copy coins.
Sorry no US one dollar GOLD coins dated 1972. A 1972 one dollar coin is a Eisenhower dollar. None were struck in gold. Many have been privately plated with small amounts of gold and sold as collectibles but are actually only worth a dollar.
A nickel is worth 5 cents so there are 7200 nickels in 360 USD.
Ike $1 coins have never been struck in gold. There are many private companies that plate them with a thin layer of gold and sell them as so-called "collectibles". However coin collectors consider these plated coins to be altered or damaged, and will only pay face value.
