10 Dinara not issued

Designed in 1951 but never released, this note was rendered obsolete before it reached circulation — Yugoslavia's monetary reform of that year restructured the entire banknote series, and several prepared denominations were shelved outright. ZIN printed the notes in Belgrade, which was unusual in that earlier Yugoslav issues had often relied on foreign security printers; by the early 1950s the state was committed to fully domestic production regardless of whether the output would ever see a teller's window.

Surviving specimens carry a "not issued" status in all major references, and unissued remainders from ZIN have occasionally surfaced through Eastern European auction channels.
