These even have substantially the same monogram as the Anastasius type, but the legends on your examples make it clear that they are issued under Justin. For the second one, possibly even Justinian? (What the heck does the monogram stand for then?) This suggests to me that, without a legend, it's virtually impossible to tell whether a particular piece is Anastasius or Justin. Would you agree? I knew there were some "nummi" issued under Justinian in the west, but I didn't take the denomination that seriously. Now I will. And it seems the denomination lasted in the east a lot longer than I realized.
