The Inti replaced the Sol de Oro at a rate of 1,000 to 1 in February 1985 during President Alan Garc\u00eda's first administration, as part of an attempt to control hyperinflation. However, the Inti itself suffered severe hyperinflation, with inflation exceeding 7,000% annually by 1990. The currency was replaced by the Nuevo Sol in 1991 at a rate of 1 million Intis to 1 Nuevo Sol. The note's imagery reflects the Garc\u00eda government's nationalistic economic policies and emphasis on indigenous heritage. The front depicts industrial textile production while the back honors T\u00fapac Amaru II, linking modern economic development to Peru's indigenous resistance history. The specific printed date of June 26, 1987 on this note places it during the period of economic crisis that would ultimately doom the Inti currency.

The choice of Świerczewski as a banknote subject was controversial even during the Communist period and became more so after 1989, as his role in Soviet-imposed Communism was re-evaluated.",

The note bears the inscription 'NARODOWY BANK POLSKI' (National Bank of Poland) and denomination '50 PI\u0118\u0106DZIESI\u0104T Z\u0141OTYCH' (50 Fifty Z\u0142oty). This design represents the late Communist-era Polish currency issued under the People's Republic of Poland before the democratic transition and currency reforms of the 1990s.", "back_description": "Karol \u015awierczewski (1897\u20131947), Polish and Soviet military officer, Communist general who served in the Spanish Civil War (as 'General Walter') and later in the Polish People's Army. He was Minister of National Defence of Poland and a Hero of the Soviet Union. \u015awierczewski was assassinated in 1947 in southeastern Poland, likely by the Ukrainian Insurgent Army. The note shows him in military uniform with his characteristic peaked cap, alongside the Polish eagle emblem. His appearance on this 1988 note reflects the Communist government's veneration of Soviet-aligned military figures.", "historical_notes": "This 50 z\u0142otych note was issued on December 1, 1988 ('WARSZAWA, 1 GRUDNIA 1988' printed on back) by the Narodowy Bank Polski during the final years of the Polish People's Republic. The series featuring Karol \u015awierczewski was introduced in 1975 and continued through 1989. This particular variant (P-142c) is distinguished by its signatures and serial number format. The note circulated during a period of economic crisis and hyperinflation that led to currency reforms. It was demonetized when Poland introduced the new z\u0142oty (PLN) at a rate of 10,000 old z\u0142otych to 1 new z\u0142oty in 1995, following the democratic transition. The choice of \u015awierczewski as a banknote subject was controversial even during the Communist period and became more so after 1989, as his role in Soviet-imposed Communism was re-evaluated.", "language_script": "Latin", "languages": "pl", "serial_number": "GW 6375990", "serial_prefix": "GW", "serial_suffix": null, "replacement_note": false, "replacement_indicator": null, "condition_grade": "XF", "condition_notes": "Note appears to be in excellent condition with sharp corners and minimal handling marks.

The design shows a stylized representation of the eclipse with planets of the solar system (labeled 'ECLIPSA TOTALA DE SOARE' — 'Total Solar Eclipse'), orbital paths radiating from a central black disc representing the eclipsed sun. Romania lay in the path of totality, making this a significant national event; the note's innovative polymer design and astronomical theme marked a departure from traditional portrait-focused banknote design. Text 'AUGUST 1999' appears in the design field, referencing the month of the eclipse.",

The portrait shows Eminescu in formal 19th-century attire with a bow tie. Accompanying the portrait is a quill pen and wheat ear symbolizing literature and the agricultural imagery present in his poetry; the BNR monogram appears in the design field. Eminescu's legacy as Romania's greatest poet makes him among the most honoured cultural figures on Romanian currency.",

The series represents a unique moment in Romanian numismatics when the note's primary subject is an astronomical event rather than a historical figure, though Eminescu appears on the reverse. The note was printed on polymer substrate with advanced security features including a holographic foil patch showing the eclipse. Date '1999' is printed on the front alongside 'AUGUST 1999' within the eclipse design; the back shows '1998' near the denomination, likely indicating design preparation date. The series remained in circulation until July 1, 2005, when Romania redenominated its currency at 10,000 old lei = 1 new leu (RON), removing four zeros.

The design shows a stylized representation of the eclipse with planets of the solar system (labeled 'ECLIPSA TOTALA DE SOARE' \u2014 'Total Solar Eclipse'), orbital paths radiating from a central black disc representing the eclipsed sun. Romania lay in the path of totality, making this a significant national event; the note's innovative polymer design and astronomical theme marked a departure from traditional portrait-focused banknote design.

The portrait shows Eminescu in formal 19th-century attire with a bow tie.

The series represents a unique moment in Romanian numismatics when the note's primary subject is an astronomical event rather than a historical figure, though Eminescu appears on the reverse. The note was printed on polymer substrate with advanced security features including a holographic foil patch showing the eclipse. Date '1999' is printed on the front alongside 'AUGUST 1999' within the eclipse design; the back shows '1998' near the denomination, likely indicating design preparation date.
