Bangladesh's first post-independence coinage series, introduced in 1974, came just three years after a liberation war that killed hundreds of thousands and left the country's economy in near-total collapse. The poisha denominations were a deliberate act of monetary infrastructure-building for a state that had only existed since 1971.

The aluminium-magnesium alloy was a practical choice for a country with negligible domestic metal reserves and a severely constrained import budget.
