Notes bearing a
"Hawaii" overprint were used during World War
II(July of 1942) to insure identification should they have
fallen into enemy hands. Types of these notes (with brown
seals and serial numbers) included $1 Silver Certificates and
$5, $10, and $20 Federal Reserve Notes. It was not until
October 21, 1944 that all currency restrictions were revoked
and normal monetary conditions returned to that area.
A
second group of notes were issued for use by the troops in
Europe and North Africa and carried a Yellow Seal (Not Blue).
Both
notes could be devalued if American forces withdrew from the
locations.
Interesting
Notes:
- The notes are dated 1934, but the US did not enter the war
until 1942
- The Hawaii 5, 10 and 20 are from the San Francisco Mint and
carry its mark on the Seal
