I have used "rare" recently for some of the chase minis like black Cram minis, and I don't think that's inaccurate, since the manufacturer itself designated those as "really rare."
And, I have used "vintage" on many occasions when listing items like action figures from the 1970's and 1980's to distinguish my items from recent issues. There's a huge difference between a 1983 Jedi Luke figure and something Kenner produced two years ago. And when I was still buying older figures, I actually used to search using that word along with other descriptive terms. Even with Wackys, to me "vintage" means anything before ANS, or at least before 1991.
Just my 2 cents; those words in descriptions don't make me run.
