1 Boliviano Law of July, 20 of 1928 First issue

Bolivia's Banco Central was only established in 1928, created specifically to unify and rationalize a monetary system that had long been fragmented among private regional banks. This 1 Boliviano was among its first issues — P#118 carrying series that run from A through R4 documents an exceptionally long print run stretched across multiple years, with four distinct signature combinations marking successive administrations of the bank's senior officers.

The progression from Granier through Arce in the presidency slot, alongside rotating cashiers and managers, means dating a specific note requires reading the series letters carefully. K3 onward represents a different institutional moment entirely.
