Does it really matter? There are those who collect cars, stamps, tobacco pipes, knives, sea shells, wine, coins, art/paintings, etc. Some collections can be more useful than others, such as cars or knives (if functional); the same with firearms. There can be both intrinsic or historical value, but most here agree that many don't "collect" firearms as a monetary investment. Some firearm owners like a particular genre of firearms (such as Mausers, other WWII firearms, Western-styled collections, etc.), but ultimately it's a very subjective definition. I have a significant number of firearms (over 100), but don't consider it a collection more than a diversified hobby of shooting firearms. I've known some people with extensive art or wine collections and admire them; they're not what I care too much about, but I don't think of them as hoarders or excessive collectors (and some of their collections involve a significant investment)...it's their hobby and they derive enjoyment out of them...same with me and firearms.
