Once upon a time I posted some "Russian" beads at what I thought was a reasonable price, and got pushback about "devaluing" heirloom beads.
So now I guess at a price based upon rarity, mostly, and figure if someone really wants something, they'll make an offer and we can work it out from there.

Someone who wants something because they really like it is, I feel, in a different bargaining category than someone who's just trying to get a deal so they can profit from reselling it themselves.
