Rarer than the usually imitated series, here is an anepigrahic / CONSTANTINVS AVG imitative AE4. Fanciful mintmark, reverse legend and bust.
Very nice...I don't recall seeing an example before.
I know only one other coin like this one which can be considered as an unofficial strike.

Poor style compared to official and unknown mintmark with this (same) dot.
