Good morning CCF, I usually stick to Lincoln Cents but found this in spare change and wanted to post it for thoughts and/or comments.
What I am seeing is on the Reverse is a Major Die Crack running from the right edge at 90 degrees right along the base of Monticello all the way across to the left edge at 270 degrees.
I have not tried to "preserve" it because I don't know what is recommended to spruce up a nickel.
It also appears something else may be going on (doubled?) but not sure and hoping you all can help identify what it is. Thanks.
