Some handguns are high-priced because there is supposedly more that goes into them in the way of craftsmanship and labor to produce better triggers and a higher level of inherent accuracy and other things as well. But if you don't appreciate those things, which may not be there anyway, then it become a bad value for you and overpriced. The same thing can be said for other things, like engraving or a special non-factory finish.
Again, not about handguns, but sometimes expensive things can drop like a rock in value because of some little detail like ammunition availability, assuming there isn't the collector interest to maintain the value. Supposedly those fine British double rifles could be had fairly cheaply when the ammunition became scarce. But fairly cheaply is a relative term and anyway, I never saw one. Among handguns, apparently there is enough collector interest to maintain fairly good prices on Walthers pistols chambered in 9mm Ultra and probably also the French 7.65 long automatic pistols. But something in, say, 9mm Federal or 9mm Bergmann might be a hard sell.
