Stopped by a small bank in town today and asked for half dollar rolls. The nice ladies there went back to the vault and brought out $170 of customer rolled halves. I was happy to get them! When I got home, it seemed pretty clear these were another coin roll hunter's dump rolls, many were marked with paint and crimps. I stopped searching after about half way through, then later figured might as well search the rest. To my surprise, I found a nice '69 Kennedy the previous hunter must have missed! Made it a fun hunt anyway!
So, after a little closer look, these are all mostly early 70s, especially '71s. Many look BU, I'll have to search these again.
There's a lot of varieties to look for in the early clad Kennedy halves. NGC VarietyPlus is a good source: https://www.ngccoin.com/variety-plu...ollars/kennedy-half-dollars-1964-date/?page=1
