Postage prepayment by the "paid-in-cash" method is not unusual during times of war and political upheaval.
This method has been used when a transition of power takes place from one regime to another or during currency reform. In those situations all mail had to be brought to the post office for prepayment. Receipt for postage was then noted in manuscript or by a rubber stamp on the item mailed. Usually the postal clerk initialed the notation, and if available, a regular postal cancel or date-stamp was added. In Estonia, the "paid-in-cash" prepayments took place in four different time periods:

The partial occupation of Estonia by the Russian Bolshevist troops during December 1918 and January 1919.

The period of the initial organization of the Estonian Postal Administration in November and December 1918.

At the beginning of the Soviet Occupation in 1940.

At the beginning of the German Occupation in 1941.

The "Estonia Philately & Postal History Handbook" by Vambola Hurt and Elmar Ojaste (in English and German) gives additional information about the Estonian "Paid-in-cash" markings.
