Thanks so much for your reply. Yes, we do have complete sets. And, of course, after we posted, we saw that someone has a set for $9.00 currently on eBay and that among the completed auctions, one set sold for $28.00 but another sold for under $5!
Thanks so much again. We may put one on eBay and see what happens -- at least the postage won't be too bad if it sells.
