Serbia's Postal Administration stepped in as an emergency currency issuer in 1915 as the country's banking infrastructure collapsed under the combined pressure of the Austro-Hungarian invasion and the devastating typhus epidemic that had already killed tens of thousands earlier that year. These postal notes — sitnice, as the small-denomination fractional pieces were called — were a stopgap measure, never intended as a lasting monetary instrument.

The Kingdom would cease to exist as a functioning state within months of this note's issue, following the catastrophic autumn retreat through Albania. Most of these pieces were lost to that collapse rather than redeemed.
