Hell, if it sits on the shelf it's just aging more. Maybe not in the barrel but still. I'd love to see the prices drop but when the base cost to distill is constantly rising it won't likely happen.
I picked up a pair of Dry Fly Triticale Straight Whiskey bottles from a limited first run in 2017 and still have one bottle cellared. $75 ea but my unopened I could get over $250 for now. The limited runs can be really good and well worth the cost, but some just don't cut it or seem rushed with the quality.
bottles on the shelf are getting older, but not aging any further. And the value goes up not as the whiskey has got older, but rarer.
Like the bottle you have cellared.
But as you say, a limited bottling does not mean the product is quality.
