Only difference I see is the fist coin has a deeper cut at the base of the rock. the last pic its much thinner. Also weather these things are within tollerence in US I know not the arrow to the left on the first coin . If you draw an imaginary line through the center of 1 down to the teeh below and the same at the tip of the arrow the first coin covers 8 full teeth from center of 1 too arrow tip. 2nd coin the distance is 8 1/2 teeth .
