Very poor quality but I enjoy the chase.
Since first posting this I've been researching...
The tripod is a clue - there are numerous examples in Greek and Roman coinage - but the latter all/mostly seem to be in Roman provincial coins (E. Empire)
Its brassy - orichalcum - which was only used in coinage by Rome late republic to (according to once source) 161 AD. Not later.
One responder so far has suggested its a quadrans and I have been able to confirm that quadrans in orichalcum exist.
So... A Roman provincial quadrans sometime in the 1st or 2nd cent AD.
Does that make sense?
Diameter: 11-13mm (varies)
Weight: 1.8 grams
Brass?
One long shot included because tracing faint outlines is sometimes easier when its not a close-up.
