I would say that entirely depends on your personal consumption habits, but...if you're like me, it would go something like this:
~100-300 singles laying around, ranging from things to grab every day to smoke, rare/HTF singles, or smokes I picked up to try (I always buy 3 when I try a new smoke), gifts, etc etc.
~20 20/25 count boxes of cigars I know I like, because when I like something, I buy in bulk to get better prices.
~5 50-cabs of smokes I love and just can't stop buying (*cough* Partagas Shorts)
~100 three & five packs of various smokes, same deal as boxes, but these are usually something at the extreme ends of the price range (too expensive to buy a lot, or so cheap I bought a ton)
So overall I'd say for a mass buyer like me, 1500-2000 sticks total, of which I probably smoke 300-500 per year and give away another 300. Many of those are sitting there, not being smoked, but that's more a factor of having too many options or forgetting about boxes of things I have than a factor of attempted aging
