 He estimated from the size of the crater that the meteorite had a mass of 100 million tons.The current estimate of 300,000 tons for the impactor is less than 1/300th (0.3 percent) of Barringer's estimate.Iron ore of the type found at the crater was valued at the time at US$125/ton, so Barringer was searching for a lode he believed to be worth more than a billion 1903 dollars.
