Im maybe to much suspicious on some coins, but for me, the 4rth is obvious fake
. For other coins: the 3rd look to me not in real silver. For the frist and second coin they share the same dies, similar 80% form of blank, centering.. the same light around the portraiture, same spot around letters ANV on the obverse
(this can be a spot on riginal die wich print it then). This is more clear when you open it in two windows and switch fast the coins.. same light, spots.. What do you think about it?
i let the photos in order of the message description.
