There is one 77d that was mentioned. I'm just asking for y'all to view more into one penny 77. I did everything what to look for. Im asking for more on this cause only one is known and mine show everything in the book and what the die would be
One more pic and Italy8686 may get 86'd from CT. No, all is good. I'm with Masterswimmer in admiring 86's tenacity. You cast that line in the water enough times and eventually you're going to snag something of significance.
For that 77D look at: http://www.varietyvista.com/12 Kennedy Halves/DDO Detail Pages/1977DDDO001.htm Your 77D doesn't present the same lines through the lettering as shown in the Vista Variety TR pic of Trust and the UR pic of Trust. Also, your D mint mark seems flattened down from circulation. Are the '82s you show brass or zinc? They show normal scratches & wear through the lettering that I see, not from doubled die. As others have stated, maybe a little MM on these. On the '81 I only see a bit of doubling on the WE.
