This 3.50% Cartella al Portatore of 5,000 lire, belonging to Series 21 and numbered 2338151, is a sovereign bond of the Kingdom of Italy issued by the unified State after the 1861 Risorgimento. The 'cartelle' were long-term Italian government bonds, equivalent to French rentes or British gilts. The 3.50% rate and Series 21 likely place this issue between the 1920s and 1940s. This document is the first in a series of five Italian certificates (items 94 to 98) which together form an exceptional documentary set on the public debt of unified Italy since the 19th century.
