At the risk of overreaching myself I will try and clear it up:
The original and obvious
attribution is to
Claudius,
his father.
However because much of the restoration coinage of
Titus and
Domitian has been linked to a
mint probably located in
Thrace. it was suggested that the
Britannicus coins were
part of this series - it is mentioned in the ancient sources that
Titus was a childhood friend of
Britannicus, so the theory was that
Titus was honouring
his old long-dead friend by adding him to the list of
restored coins. The Brittanicus
type does not bear the "REST" that appears on the
Flavian coins.
However there is also a group of bronzes (see above) that are also attributed to that Balkan
mint, so it seems more logical that the
Britannicus coins belong with these, and we are back with them being struck under
Claudius. There may be other relevant evidence that I am not aware of.
