Hey, fellow Kentuckian! Didja know there are three of us signed up now?

Before I get to the use of the word, I'll reiterate my gripe about the spelling. One way or t'other, and preferably the right one! Danged confusing, mutter...

I would also like to see its use as a noun dropped, if all it's going to mean is that somebody wants you to spend your money. Danged greedy people, grumble, mutter...
But then again, maybe we should keep it, for, as you suggested, it already has the connotation of something manufactured to be marketed as such.
I can't think of a single-word term for something valuable that one can collect.
