On the reverse there is a lineal marking starting at the rim by the O in one and continuing the the opposite rim. Bizarrely it comes up through the D in dollar and back down through the O. I have never seen anything like this before, so over to you guys with all the knowledge
@expat It just looks like some oddity that has discolored the coin. Going over then under the "D" and over then under the "O" of DOLLAR rules out a strikethrough of any kind for me. ~ Chris
