This is a 1000 gram (1kg) iron bar.
Its raw value is around $100.
If you decide to make horseshoes, its value would increase to $250.
If, instead, you decided to make sewing needles, the value would increase to about $70,000.
If you decided to produce watch springs and gears, the value would increase to about $6 Million.
However still, if you decided to manufacture precision laser components out of it like ones used in lithography, it would be worth around $15 million.
Your value is not just what you are made of, but above all, in whichever way you can make the best of who you are.
