50 Nakfa

Eritrea's 1997 series was the country's first domestically issued currency following independence from Ethiopia in 1993 — the nakfa itself named after the northern town of Nakfa, which the EPLF held throughout the long liberation war and came to symbolize resistance. Giesecke & Devrient had a long record of printing currencies for newly independent African states, and Eritrea's assignment to their Leipzig facility reflected standard post-reunification consolidation of the firm's East German operations.

Clarence Holbert's involvement is worth noting — he worked extensively on African currency design through this period, producing work for multiple issuing authorities. The security specification here is modest: a single watermark, no metallic thread, no color-shifting ink. Practical for a young central bank with limited procurement budget.
