Quite badly beaten up, this one, but there's a dot in the middle of the
reverse. This dot is
good thing, because it narrows down options a lot.
In addition, I think I can read TS in the
exergue beneath the victories and that means it is possible to identify the coin quite well.
On basis of all that, this is a coin of
Constans, the
obverse legend should read
CONSTANS - PF
AVG and be struck at
Thessalonika,
RIC 101, full
mintmark SMTSA or
SMTS delta
If I read the TS wrong, then it is
still a coin of
Constans CONSTAN-S PF
AVG due to the trace of
obverse legend and in that case it is struck at
Siscia,
RIC 185, mm .BSIS.
Usually it is difficult to say anything more specific about coins in such condition, but there're some clues on this one.
Clueless
