200 Dinara DP Željezara Zenica, Zenica

DP Željezara Zenica was a state-owned steel mill in central Bosnia, and this note is a factory token currency — a bon — issued for use within the enterprise's internal payment network. Such workplace scrip was not unusual in Yugoslav socialist industry; large kombinats often issued their own denominated vouchers redeemable at factory canteens, workers' shops, or for advance wages. What distinguishes this piece is that it was printed by Zavod za Izradu Novčanica, the official Yugoslav banknote printing works in Belgrade — the same facility that produced the national currency. Full security paper with watermark, not the cheapstock used by smaller enterprises.

The use of filigree paper and a proper watermark on what is essentially industrial scrip suggests an order placed through official state channels, probably to prevent internal counterfeiting at scale.
