Don, FYI, there is at least one chip from the QE2:
$5 dark red with 5-1/4 dark yellow inserts, scroll mold with gold hot stamp "Queen Elizabeth 2...$5"

I don't have it handy to scan right now. Picked it up 5+ years ago, though don't know its age. Have seen it at shows occasionally, but not common. May have been in one of GA's auctions at one time too.
