I belong to your league in determining doubled dies. In due time, you and I will know and learn real doubled dies from CCF with the experts help.
Looking from your pictures, I think you have a die crack from the rim to the left base of the Memorial. And in the left upper corners, you have heavy die abrasions, in addition to Mechanical Doubling (MD) as mentioned by John1.
You do roll hunting which means you have a lot of patience. Keep on roll hunting... you will find better coins...
Enjoy the hobby...
