Pulo - Pyotr Dmitrievich

Dmitrov's coinage in this period reflects the principality's awkward position between Muscovite expansion and Tatar suzerainty. Pyotr Dmitrievich, son of Dmitry Donskoy, ruled Dmitrov as an appanage prince — technically subordinate to Moscow yet maintaining enough autonomy to issue his own copper pulos, the small-denomination coins that greased local market transactions while silver remained scarce or hoarded.

The Zaitsev classification places this type firmly within the early appanage coinage sequence, a series that collapses quickly after Vasily I consolidated Muscovite authority over the surrounding principalities in the 1420s.
