Trade value might be all over the place. These were super limited, like stores only got a single 12 pack case, and sold out fast. Someone who drove around all day to get a single bottle might have unrealistic hopes for that 1:1 kbbs, while others might simply go for $4$.
Nothing crazy on the value...$4$ for other semi-limited brewery or shelf beer. What are you looking to get for them? Then we can tell you if it's realistic.
