| 备注 |
The Banque Impériale Ottomane — founded in 1863 under joint Anglo-French capital and holding the Ottoman note-issue monopoly — produced this 20 Kuruş during one of the empire's most acute fiscal crises. The Russo-Turkish War was looming, state debt was spiraling, and the Porte had already suspended external debt payments in October 1875. Small-denomination paper issues like this one were part of a desperate effort to manage liquidity when hard currency was being hoarded.
The ink stamp security feature is characteristically rudimentary for the period — and notoriously easy to forge, a vulnerability that plagued Ottoman small notes throughout the 1870s.
