At the beginning of the war all hard currency or U.S.coins were hoarded and disapeared from circulation within a few months. In order to continue business transactions private companies and counties were allowed to issue notes redeemable at their businesses or offices usually in sums of either 5,10,25,75 cents and 1,2,3 dollar. All are of course quite rare today.
