10 New Sen Red and green

Indonesia's 1949 10 New Sen belongs to the emergency currency issued by the Republican government during the Dutch military actions — a period when the Republic operated a parallel monetary system from its interior strongholds in Java while the Dutch administered coastal and urban areas. These notes circulated under genuinely contested sovereignty, not as peacetime administrative currency.

Pick 35 is among the lower-denomination Republican issues whose survival rate is disproportionately poor relative to higher values, largely because small notes saw the hardest daily use and were rarely preserved.
