What does this phrase mean?  As in, for example:
You wouldn’t want to be dead for quids, written after a congratulatory note.  And how long has it been around?

Edit:  A small champagne would be nice.  (I get one of me eddicks if I have too much of the stuff).  I’ve reached treble figures.

And with your very next comment you’ll get your third box!  (Sorry, no idea about the quids.)

< pop! >

Rummaging around the net, I get the impression that it means “Life is so good, I [or you, depending on the phrasing] wouldn’t agree to be dead even if somebody paid me [you] to be.”

Another quids phrase, expressing satisfaction for having turned a tidy profit: quids in!
