Russia
World War I Currency Stamps
Low value in a set of three stamps issued in October 1915
One of two surcharged values in a set of five stamps issued in 1916-1917.
During World War I the Russian government responded to a shortage of coins by issuing stamps that were printed on light cardboard for use as currency. The designs of stamps issued in 1913 to commemorate the tercentenary of the Romanov dynasty were used. Although it was against regulations, the ungummed stamps were sometimes used for postal purposes. The inscription on the back of the stamps translates, "Having circulation on par with silver subsidiary coins."
