http://www.beeradvocate.com/community/search/30078979/?q=fen tao&o=date&c[node]=25 There's like 30 trades posted in the last day. That should give you a good idea.
I have been regularly trading Jk $4$ for the past month. Its all brewery only for the most part. I guess Idk what the "equally limited" beers are. Idk how many bottles of everything was made. But thanks anyway
I personally don't think "bottle count" is as important as most other traders. For starters, unless it's the same size/maturity brewery, they very likely can't make more bottles even if they want to. I find Jester King & Hill Farmstead to be very similar, and they trade well against one another. I think Allagash wilds also are a good barometer.
The better question is - what do you WANT to get? Don't focus on "value" - if there are things you are interested in trying or looking for, post them here or just put up a trade offer and see what happens
