20 Unopened Uncirculated US Mint Rolls Of Kennedy Half Dollars

I went to my other branch bank this afternoon. While waiting in line I saw and heard a woman drop off to the male teller some large heavy coins. I asked for any Half Dollars, large dollars, and nickels he didn't have nickels but he said a lady just deposited some. I said I'll take them all. He said, "you won't find any silver in these, do you still want them. I responded, of course, I'm looking for NIFC's for my collection. He then produced a bag of $200.00 neatly wrapped unopened uncirculated U.S. Mints Kennedy NIFC's. The loose coins included an impaired proof 1978 S. A couple unremarkable Ike's and no silver. However, the rolls included the following 2001D (not NIFC), 2002 P&D,2003 P,2004 P&D, 2015 P&D, 2016 P&D, 2017 P&D 2018 P&D, 2019 P&D, 2020 P&D2021 P&D. I really needed the 2015-2020.
