These are my last two medievals, please help what could they be. Can't even tell which way to look at them. Will never again buy medievals, what a nightmare trying to attribute those. Perhaps a shield with a horse rider on this one? 13 mm, 0.450 g and this is the last one, seems to be silver, the reverse is very worn: 7 mm, 0.503 g I am very very grateful for any suggestions.
