2500 Piastres Siege of Khartoum

Issued during the ten-month siege that ended with Gordon's death in January 1885, this note is among the most historically charged pieces of paper money ever produced. With Khartoum cut off by Mahdist forces and the Egyptian treasury unable to resupply, Gordon improvised an emergency currency on whatever materials were available, backing it on his personal authority as Governor-General rather than any functioning monetary institution.

The printing was done locally under siege conditions — no security printing house, no engraver, no trained press. Gordon signed each note himself. That signature is the only meaningful authentication device the note possesses, and it is also what makes forgery during the siege a near-irrelevant concern: everyone in Khartoum knew what Gordon's hand looked like.

Wolseley's relief column arrived two days after the city fell.
