Oh sure, those valuations are BS, that website is promoting something. Price is dynamic, a function of supply-demand. It's why DeBeers stores diamonds in vaults - if they could sell them at current prices they would. Since iron is relatively abundant on earth, I think the cost of iron is in processing. Space iron is far, far more expensive to process than earth iron ore or earth iron salvage. I looked up shipping costs for example on nasa.gov and they don't even list a number, instead they quote CALL ME. You know the prices are steep when they don't list them.
