I thought it was the British pound and there is no such thing as a Doller. Currencies within themselves have no intrinsic value. Their value is either relative to the value of gold or to each other. Therefore your question makes no sense.

If you mean has the American dollar weakened substantially against the pound and other currencies. The answer is yes.
