Where does the word quid come from -meaning a pound?

maybe from Latin quid pro quo; see here near the bottom.

...mmm..jno, I like another explaination on that page better......"However a more interesting origin is that the 'quid' might well derive, additionally or even alternately, from the now closed-down Quidhampton paper mill, at Quidhampton near Salisbury in Wiltshire, South-West England, which apparently many years ago manufactured the special paper for the production of banknotes.....like it!  commoner :-)
