I thought ide post this one as it may be of interest to some of you. It's an 1863 penny with a dot, well a dash really under the D in F D in the shape of a half round dot.
I'd say a plain 1865. The 3 isn't fully curved, it's the type with two straight lines for the upper, so a 5/3 shows a straight line angling down from the top right to where the 5 begins to curve. I see no trace of that. However, it's a very nice 1865.
