The United States government banned private ownership of gold, which lasted 41 years; then lifted it on December 31, 1974.
Governments fear gold because it competes with their own paper currency as a viable and preferred means of exchange AND a store of value. (Dollar devaluing and gold rising currently. Maybe they might decide to put in place the ban again!)
A one-ounce gold nugget is more rare to find than a five-carat diamond
Gold is so heavy that one cubic foot of it weighs half a ton
Gold is six to seven times heavier than other materials that equal its size
Gold can be hammered so thin that sunlight can shine through it.
A single ounce of gold can be drawn into a wire 60 miles long
Gold can be hammered into sheets so thin that a pile of them an inch high would contain more than 200,000 separate sheets
In every cubic mile of sea water there is 25 tons of gold! That's a total of about 10 billion tons of gold in the oceans; however, there's no known way to economically recover it. (if anyone discovers a way, please call me!)
The hardness of pure gold (on moh's scale) is 2-1/2 to 3; the melting point is 2,063 degrees Fahrenheit, specific gravity is 19.32, and tensile strength is 19,000psi
Gold can be transmitted from platinum by nuclear reaction. But, because of the rarity of platinum, it is far too costly.
South Africa is the largest producing gold country in the world today
Gold is chemically liquified and injected into the muscles of thousands of rheumatoid arthritis victims in the U.S., and it is said that the treatment is successful in seven out of ten cases.
Gold is used in window glass and astronaut helmets to reflect infrared rays while allowing sunlight to pass through, and at the same time keeping it cool.
Gold is inactive chemically and is not affected by air, heat, moisture and ordinary solvents. (so never tarnishes, unlike silver)
