4000 Pesos Bolivianos Year of the Child, Piedfort

The 1979 International Year of the Child was proclaimed by the United Nations General Assembly to mark the 20th anniversary of the Declaration of the Rights of the Child. Bolivia was among the nations that issued commemorative pieces tied to the event, though the piedfort format — struck at double the standard die thickness — was produced in extremely limited numbers and intended purely for collectors rather than any commemorative circulation. Piedforts of this period from smaller issuing nations rarely appear at auction.
