Personal opinion is that if you're just looking to collect for the sake of increasing your financial gain in the long run, you don't really care or value what you're collecting outside of the object's monetary value. May not be a popular opinion, but yea. I don't buy/collect things I don't hold some personal value on, whether it be a part of my childhood, my hobby or just something I absolutely love.

If not, what's the point? Just throw it in a closet to never see the light of day until you see the market value raise, just for you to sell it off for a much higher premium to the people that actually care about it, without the intent of resale for further financial gain?
