I have noticed something unusual on two 1980 D S.B.A dollars today. sorry , I have no access to a camera, so i'll try to describe them the best i can. Below the LIBERTY there are three stars, in between the stars, there is a raised zig-zag line. Any one know of this? Any value to this? Any help is greatly appreciated.
Howdy claw - Welcome to the Forum !! Based on your description it sounds like a die crack. Typically it does not add value but some do like to collect them.
