During World War II, the U.S. government issued specialized emergency issue notes for Hawaii and North Africa. These weren’t typical Federal Reserve or silver certificates—they featured unique seals, overprints, and designs created for strategic wartime purposes. Today, they’re highly prized among collectors and history enthusiasts.
This article explores what makes these notes so valuable, detailing their background, rarity, key features, price trends, and collectible appeal.
History & Purpose of Emergency Issues
Hawaii Emergency Overprint Notes
Trigger: Pearl Harbor Attack (December 7, 1941)
Following fears of a Japanese invasion, the U.S. military recalled regular currency in Hawaii in early 1942. The solution: distinctive emergency notes marked to devalue in enemy hands.
Features:
- Denominations: $1 silver certificates; $5, $10, $20 Federal Reserve Notes
- Characteristic brown treasury seals and “HAWAII” overprints on both front and back
- Issued from 1942 to 1944; recalled by April 1946
North Africa Yellow Seal Notes
Trigger: Operation Torch (November 1942)
To control currency in North Africa, a special note series featuring bright yellow treasury seals was printed. This signaled military authenticity and served as an anti-counterfeiting measure.
Features:
- Mostly $1 silver certificates (Fr. 2306 series)
- Yellow seals, no geographic print but used exclusively in the military theater
