1 Escudo - Carlos III

Carlos III's reign saw the Santa Fe de Bogotá mint operating under considerable administrative pressure from Madrid, which was restructuring colonial minting operations across the Americas following the Seven Years' War. The escudo series of this period is complicated by assayer transitions — the KM#42 grouping spans multiple assayer marks, and Hernández's tighter split into #678–679 reflects documented differences in die workmanship that casual inspection can miss.

The Bogotá mint was chronically understaffed relative to its output demands throughout the 1760s, a condition that occasionally shows in planchet preparation rather than the striking itself.
