Not a strike through,this is just discoloration of the cent maybe from circulation, probably enviormental damage. JIM
I assume you are talking about the lines going up to the u in "pluribus". That is the result of gas bubbles under the copper plating. many early zincolns had this problem. Richard
A little mistake on my part sorry, Yes those lines are called elongated gas bubbles,and are commen on these cents. I thought you also were refering to the obverse were there's a planchet problem discoloration/ JIM
