Colombia's Banco de la República introduced this issue as the country's monetary system strained under one of the worst periods of narco-violence and economic instability in its history — the early 1990s saw Pablo Escobar's war against extradition at its peak, inflation running above 25% annually, and the central bank under pressure to keep low-denomination coinage practical and cheap to produce.
