How about 200+ '87 P & D's all in ch/gem BU? I got them all in 2 boxes a whole back. They are all bright, fresh off the press. Any value there?
If you can find a buyer willing to pay enough over face value when you try to sell, then they have value. The same can be said for 200 beat up bicentennials, a jar of ear wax, and a box of used paper towels. I once saw a quart sized Ziploc bag full of "Genuine Arkansas dirt" sell for ~$10 if I remember correctly.
Anything can have value, if you can find a buyer willing to pay. But, I'd be willing to bet that - generally speaking - 200 gem BU 1987's would bring no more money than 200 gem BU 1986's or 1988's.
If 100 different people tried to sell a lot of 200 gem BU 1987's, I'd speculate that some would realize a decent profit while many couldn't sell theirs over face value. To the ones able to sell for a profit, the 1987's would have had "value", and been a complete waste of time and trouble for the others that couldn't.
I might find someone willing to pay me $20 for a roll of average condition bicentennial halves...and I have VERY occasionally seen them sell for this amount on ebay. Does that mean everyone should save all their bicentennials?
"Should I save these?" (where "these" can be anything) is really an unanswerable question. The best answer I can come up with is, "Maybe." When it comes to NIFC halves, I just don't see the market ever getting to the point where anyone and everyone with NIFC halves for sale will be able to sell them for a profit.
