10 Pesos Bolivianos

The sheer number of signature combinations on this single note type — nearly twenty distinct pairings across series A through U3 — reflects Bolivia's chronic ministerial instability through the 1960s. The Pesos Bolivianos currency itself was introduced in 1963 to replace the Boliviano at a rate of 1,000 to 1, following years of hyperinflation that had rendered small denominations essentially worthless. A 10-unit note in the new system was still modest spending money, and these circulated heavily.

Thomas De La Rue's involvement guaranteed consistent print quality across a long run, but the rotating cast of finance ministers and central bank presidents signing the notes tells the real story of the decade.
