A superb, sharp and strongly struck fresh solidus with traces of the original mint luster. Some very tiny scratches and pits, otherwise, nearly extremely fine.
The quality of this solidus helps us spot some interesting details. On the reverse the X is clearly re-cut over a faintly seen Θ thus confirming the order of the issue attested in DOC.
