Don't have it for sale...
Rare box sets, I guess it's all about what you mean with rare. But here's a small list of box sets. I don't think that Britain's health resort qualifies to be box set, just cos the CD comes in a tin box, and it's not that rare...
Iron Fist in cast iron, there are two series of that, one limited to 1500 and one to 1000 (I think it was). All the aces cast iron mask (competition give away, 10 pcs made). Overnight sensation box set. Fistful of aces box set with Illustrated collectors guide (first book by Mick Stevenson and Alan Burridge). Stiff box (contains singles #buy01-#buy10, where Motörhead is #buy09) Other boxes: Protect the innocent (4CD), Born to lose live to win (10CD-single, one numbered and one not numbered), Metldown, Bronze age, Stone deaf forever, and probably a shitload of more stuff that I can't remember at 5:30 in the morning...
