Is there a general consensus on what the "rarest" LEGO set of all time is? And if so, then what is it?
To clarify, of the sets that at some point were for sale to the general public, which one is the hardest to acquire? Tour and company exclusives should not be included, as they were never "produced" to the general public. As far as what quantifies "rarity," price, number produced, current avaliability, or etc, I'm not sure, and that's why I'm asking if there is a consensus on this.
