Early Byzantine coins feature the head of the Emperor, now full face rather than in profile on the obverse, and usually a Christian symbol on the reverse.
In the 10th century, so-called "anonymous folles" were struck instead of the earlier coins depicting the emperor. The anonymous folles featured the bust of Jesus on the obverse and the inscription "XRISTUS/bASILEU/bASILE", which translates to "Christ, King of Kings".

Given that Theodosius was not raised as co-emperor until 590, it makes sense to date the coin to his reign in my opinion.
