I went to the bank after work today and was able to pick up 2 rolls of halves. Both rolls were marked. 1 marked Uncirculated 1971 D, and the other is uncirculated 1776-1976. Does these have any value?
Doubtful you could get much other than face value. If they were original bank wrapped roils that were unopened you might get something for them above face value. The problem is there are so many Kennedy halves minted - especially the Bi-Centennials. The Bi-Centennials alone make up over 14% of all Kennedys ever minted - including 2010. They are not rare.
