Well, that's if you believe in the dollar inflation. Consider the same in opportunity cost, as in, what if it was gold instead? In 1867 gold was worth $27.86 an ounce. Today gold is worth $1,289.10 per ounce (way down from last year). That means Alaska was purchased for 258,435 oz of gold. Or, $333,148,600.14 today. Still, it was quite a bargain.
