Since it's wrapped in metal, you shouldn't be in a position that you HAVE to do something right away.
As far as restoration materials go, you're not likely to reap much (if anything) from that structure. So, as far as beams and what-not is concerned, you may not see enough interest to offset the demolition.
Since it's wrapped in metal, it's been pretty well protected. Also, since it's really not a large structure (as near as I can tell), it becomes a candidate for relocation by a greater number of tradesmen/customers. A gambrel roof barn is likely more popular/desirable, but their size really limit the number of interested parties.
Your experience in NY may be different than mine in Michigan. The greatest interest in materials is either siding or the hay mow floors. You have neither.
Even without the desirable siding, in time you should be able to find a buyer for the barn. As a carpenter, you may even consider what it'd take to dismantle/reassemble the basic structure yourself.
