Denga - Peter I / Ivan V with the name of Peter

The denga issues of the co-tsardom of Peter and Ivan V belong to one of the strangest constitutional arrangements in Russian history: two crowned tsars ruling simultaneously, with the regency effectively held by their sister Sophia. Coins were struck in the name of both rulers throughout this period, though the wire-money technique — hammered from drawn silver rod and clipped to weight — was already an anachronism by the 1680s, a survival of medieval Muscovite practice that Peter would abolish entirely with his monetary reforms after 1698.
