The success of these conversions depended on secrecy,
since any leakage of an imminent C-day
would cause unauthorized users of MPC
to quickly convert their hoard into goods at the military store,
or exchange them on the black market into Piastre or Regular U.S. 'Green Back' Dollars.
According to Prugh, the first C-Day on October 21, 1968
resulted in $276.9 million in certificates being converted,
with $6.2 million going unaccounted for,
presumably because they were in the hands of unauthorized persons.
The next C-day occurred less than a year later, on August 11, 1969.
and the next conversion on October 7, 1970,
about 25% of recalled MPCs were not accounted for
2nd Civil Affairs Company was stood down on July 27, 1971
The final C-Day took place almost three years later on March 16, 1973. |
