The two letters on the platform on which the figure of Christ is standing seem to be the initials of Venetian provincial governors (or other officials, or prelates of the church) who were responsible for a particular issue of coins. For instance, a V O stood for Vincenzo Orio, the Venetian governor of Dalmatia.
On this Italian numismatic circular, names are given to each coin's initials; with a question mark if it's not 100% certain. Your coin is #315, a silver mocenigo (or lira) of Gritti, with initials BK. Unfortunately, it's the only coin on the list where they didn't give a name for the initials! Sorry!
