Steve, it's rather obvious that they aren't going to tell you. Quid is slang for £1. One pound sterling, which is now about $2USD if not a bit more.


Now, as to how it came by that, I surely can't tell you. It was the old English monetary system with all those words--quid, bob, farthing, shilling, etc. At least now it's on the metric system.

If you really want to understand the old monetary system, I suggest you PM a friendly Brit.
