1 Pengő - Miklós Horthy Red Army Counterstamp

Hungary's aluminum 1 Pengő circulated widely through the early 1940s as the economy strained under wartime conditions. At some point — most likely during or immediately after the Soviet advance through Hungary in 1944–1945 — individual Red Army soldiers counterstamped these coins with Cyrillic initials or unit markings, a practice documented across occupied territories as informal souvenirs or ownership marks. No official Soviet military order sanctioned it.

KM#519 counterstamped examples exist in some numbers, but attribution is complicated by the difficulty of authenticating the stamps themselves.
