Tetradrachm

Very informative and educational.
Thanks for posting.
I have four or five tetradrachms of Alexandria, spread over the 300 year period.

A numismatic statement of the eastern Greek part of the Roman Empire, expressed in tetradrachms.
They are good coins to have in a collection of Roman coins.
The tetradrachms are larger than the denarii of the west, and are a way of acquiring larger size Roman silver for your collection.

Thanks Ed, very interesting site.

On Roman Tetradrachms.

I've aquired this Tetradrachm of Nero, and cannot find a match online.

Weight: 10.90 g, Diameter: 28 mm.

Not a great example, the bust of Nero was either done away with by corrosion or was defaced.
The difference is the reverse.

The examples I found online have "P Omega (Upper Case) - M H" whilst my example has "P Omega (Lower Case) - M H"
