Kopeck - Pyotr I / Ivan V with the name of Peter

During the joint reign of Ivan V and Peter I — a constitutional oddity forced by the Miloslavsky faction following the Streltsy uprising of 1682 — coinage was issued under both names simultaneously. This piece carries Peter's name but was produced during years when real power rested with Regent Sophia, Ivan's full sister and Peter's half-sister, who governed until her overthrow in 1689. The wire-money format itself was already an anachronism by the 1680s, a medieval hammered tradition Peter would later abolish entirely when he reformed the monetary system along Western lines after 1698.
