In this Gold infographic everything is calculated with Gold price at $2000/oz. When Gold reaches $3110/oz, 1 oz of Gold & a $100 bill will have equal value in weight and it won't matter if you have 1oz of $100 bills or 1oz of Gold. Gold is usually measured in Troy Ounces. A Troy Ounce is about 1.09 regular Ounces.

There's surprisingly little Gold in the world & this infographic shows all the Gold ever mined. If all the gold ever mined was melted into a solid cube, the cube with sides of 20.5m would fit in an Olympic Swimming Pool. The small gold sphere, in front of the cash couch, weighs 1 metric ton exactly, with a value over $50 Million dollars.
