Hungary's postwar monetary reform of August 1946 replaced the pengő — which had collapsed in the worst hyperinflation ever recorded, with the penpengő notes reaching denominations of 10 to the power of 20 — with the newly established forint. Trial strikes in tombac were produced during the design and metallurgical evaluation phase before final composition decisions were made; the circulating 5 forint would ultimately be issued in silver. Tombac piéforts and trials from this transitional period exist in very small numbers, most traceable to institutional collections rather than open-market circulation.
