Bolivia's earliest republican coinage was struck at Potosí, the same mountain mint that had supplied Spain with colonial silver for three centuries. The transition to independent coinage was administratively chaotic — early republican issues from 1827 onward saw frequent adjustments to fineness and weight as the new government struggled to assert control over a mint accustomed to colonial oversight. KM#94a reflects one of those fineness revisions, the .667 standard representing a deliberate reduction from earlier issues.
