I quite agree. The Dalwhinnie 15 year old was first released, if my memory serves me well, in 1987, so it cannot therefore be any older than 23 years. It's a standard expression of its time as part of the classic malts range. Before the 15yo came out the standard issue was an 8yo.
It's not in the best of conditions, looks to me as if it has be kept in the fridge or in very damp cold conditions.
I would estimate its value to be between £40 to £50, may be even slightly less.
