20 Soles = 25 Pesos

La Providencia was one of several Peruvian private banks that briefly issued fiduciary currency in the early 1860s before tighter state banking controls curtailed the practice. This denomination — expressed as a dual valuation bridging soles and pesos — reflects the transitional monetary arithmetic of 1864, when Peru was still working through the practical consequences of the 1863 decimal reform that replaced the peso with the sol at a rate of 5 soles to 4 pesos.

Printing in Lima rather than abroad was unusual for private Peruvian bank issues of this period, most of which were contracted to European firms. That domestic production likely contributed to the vulnerability of these notes to forgery, a persistent complaint among Lima merchants in contemporary press accounts.
