A very interesting iconographic type of denarii of Boleslaw IV, which is difficult to obtain.
It is a type referring by its obverse to the first issues of Curly - with a reliquary - depicting the ruler in front, on a throne. Perhaps the reference to a widely recognized coinage was to facilitate their acceptance in circulation. Unlike them, however, the sword here is raised, instead of lying in the prince's lap.
The reverse is also very interesting - with a rare depiction of what is most likely a mythical creature (described by some researchers as a griffin or pegasus).
The issue dates to the years after 1166.
An uncirculated piece, with a luster on the obverse, only carelessly minted.
