I have found a 1964 D Jefferson that appears to have a ghost impression on the reverse. I have pennies and dimes with this, but this is my first for a nickel.

Thanks Paddyman. It is hard for me to believe that all these beautiful coins have been sitting in Band-Aid boxes, coffee cans, etc. for 50, 60, 70 years waiting for me to get to them.
