             Coin production is often suspended during war time, as metals are 
              required to make weapons. Other materials are therefore used. A 
              common substitute is a mounted postage stamp. This 10-cent postage 
              stamp was used as currency in Italy during the First World War. 
              It has been mounted with a frame to protect it, which has been stamped 
              with an advertisement for Singer’s sewing machines.
