8 Soles

Bolivia's 8 soles issues of this period were struck at the Potosí mint, sitting atop the Cerro Rico at over 4,000 meters elevation — the same mountain that had been hemorrhaging silver into global trade circuits since the Spanish colonial period. By the 1840s, Potosí was well past its colonial peak but still functioning, supplying coinage to a republic that had only declared independence in 1825 and was still assembling the basic machinery of a national monetary system.

The .903 fineness reflects a deliberate step down from colonial-era standards, adopted as the new state balanced metal costs against the need for circulating currency across a landlocked and sparsely connected territory.
