The meaningless legends are typical for the first years of
Maurice at
Antioch mint and partially because of
his name resemblance to the formewr emperor
Tiberius II and because of the fewer and fewer people who
still knew latin in
Syria. Your example is a post-reform issue (besides introducing the correct
legend the uncial M was replaced by a capital M). On your coin there is a simple mistake by reversing letters. Probably they just copied an old
legend and didn't know any more what it stands for. This kind of errors often occur in this period.
This is an year
XII from my
collection.
