Last August, I went to this bank near my house and bought about $200 in halves. Two rolls were all 90% silver, Kennedys, Franklins, and Walking Liberties. And this was my first time roll hunting too! I went to the same bank again last December and they had another $150 in halves. One roll was mostly 90% silver with some 40%. Some of that 90% was again Franklin and Kennedys. I went a third time earlier this month and they only had $20, but there was nothing in it.
Because of my half-dollar hunting (at that bank and various others), I now have a complete collection of
Kennedy half dollars 1964-2001 except the 1970-D, 1982-D, 1987-P, 1987-D (not inlcuding proofs, and I did find a 2005-D and a 1984-S in really good condition).
In addition to saving aside the best of each date (including the Franklins and Walking Liberties), I still have a whole roll of 90% halves + 15 more 90%s, and I am just one short of a full 40% roll. I plan on trading them eventually for other silver coins (maybe to complete a
Franklin half dollars series).
