It doesn't continue to "age" in the sense of getting flavor from its barrel, but there are chemical reactions still occurring in there, though the chance that they'll change the flavor is small (something drastic would have to happen like exposure to oxygen or severe heating).
However, there is a market for as-bottled vintages of whiskey, especially single-malt scotches, but not exclusively, because blends can also be slightly different from year to year (even though the point of blending is to remove those inconsistencies, blends are tasted by people, and people are only slightly more consistent than barley and oak).
Crown Royal might be high-end enough to fit into that market.
Super-expensive for what is essentially a chance to taste a "different" whiskey, when there are already hundreds of different whiskeys, but the people who've grown bored of all the usual suspects and shire-based puddlings get a bit wonky over this stuff, which leads to the ability to charge huge multiples of the bottled price for a chance to sip and hoard a rarity.
Your 1968 Crown Royal could just be unique.
