2 Afghanis

Afghanistan's 2002 currency reform was the most ambitious redenomination the country had attempted since the 1970s — the new afghani replaced the old currency at 1,000 to one, collapsing a spectrum of competing regional issues that had proliferated under warlord control during the civil war years. De La Rue printed the new series in a tight production window to meet the rollout deadline set by the transitional administration under Hamid Karzai.

The 2 afghani is the lowest denomination that carried both watermark and thread security in the series, a deliberate choice given widespread counterfeiting of low-value notes in the preceding decade.
