Looking at
Coinarchives,
weight should be in the 12.2 to 12.4 gm range for a coin of this series with light wear. A slightly lower
weight would not be unknown, but does start to raise questions.
Style looks
fine and is certainly better that that of the common
cast fakes. The coin appears to have been overcleaned, but the various scratches, dark spots and possible remnants of horn silver at 2 o'clock all argue for genuine. All of these effects could also have been caused by the application of chemicals to a
cast coin, so I'd hesitate to say more based just on a photo of the
obverse. Anyone recognize the
countermark from published specimens?
