The US dollar hit an all-time low against the Euro less than a week ago.
Currency exchange rates are real-time, they are not historical fact. In a low-level economics class, you learn all about them, what makes a currency appreciate, depreciate, etc but it's your responsibility to keep track of current events.
You know damn well that you acquired this info regarding the US dollar online and/or on TV.
However, I don't think the US dollar was eeeeeeeever worth more than the pound or the Euro, lol so synful, what kind of business courses have you been taking?
