During the Civil War in Russia more than 3000 various denominations were issued, they were valid and accepted either over the whole territory of the former empire or in some of its regions. Some of the currency notes were really incredible and some were simply weird. Their names related to the area where they were used or to the names of local government’s heads.
Old emperor money was not out of town at all – they were put on ice and some people really hoped that the revolution would step back and those notes would come into use again. The World War I and the Revolution needed metal for military necessities, that’s why almost all the metal coins (silver, bronze and copper) of various values disappeared – so, before beating swords into plowshares, they had to beat coins into these swords. Of course, the actual value of new currency was not high, but still people had to use something for buying and selling even at the time when food used to be the hardest and most desirable currency.
A 50-karbovanets note had a lot of signatures. Almost no one believed this money was stable, and that’s why people who gave the note in exchange for some goods had to affix their signature. So, it was not the note itself and its name that guaranteed its value, but the name of the buyer.
