A very rare variant for this vintage.
Distinguished by the bust with rivets in the cuirass fittings, without volutes at the shields and large crowns in the crown rim. Additionally different from the variant illustrated in Hubert Zhukovsky's catalog, as it has rivets also in the double outline of the armor epaulet.
Nice, clear luster. In the background of the obverse, the ghost of the reverse is gently visible.
