I recently came into a few of these, and was looking for BCS their variants, or maybe older vintages. Would offering multiples of these in a trade for any of the aforementioned beers be reasonable?
In my opinion, no. While Rumpkin is a decent beer, it's nowhere close to the caliber of the beers that you're interested in.
I think a few Rumpkins could get a BCBS or a variant. Not Rare, but perhaps Coffee or Bramble. I was able to land both with beers that were similar to Rumpkin in terms of rarity/cost. I would personally be willing to trade a Coffee or Bramble for 2-3 Rumpkins if I had multiples of them (which I don't).
Really ? I picked up about 7 or 8 last year. used a couple as trade extras and drank the rest. I'd gladly give up a few Rumpkins for a Bramble but on the other side of the coin, If I had a Bramble no way I'd give it up for Rumpkin.
