5000 Ouguiya Central Bank of Mauritania

The 5000 Ouguiya is Mauritania's highest denomination note, introduced as the country's economy expanded on the back of iron ore exports and nascent offshore oil revenues. G&D's Leipzig facility has handled Mauritanian currency printing for several series, giving the BCM a reliable relationship with a single supplier rather than diversifying across multiple security printers — unusual for a central bank of comparable size.

Pick 27 represents a relatively modest security specification for a high-value note: watermark and security thread without the polymer substrate or color-shifting ink increasingly standard at this denomination elsewhere in West Africa by 2013.
