It is this coin, unfortunately still without identification.

There are some Dark Ages coins with monograms composed in a similar way, especially of rulers named Theoderic.  But I did not find any matches.  ANd for copper I tend to think of Byzantium.

I case it helps, here are some examples (the first with similar letters, the last less so)
