Auction # 2433 ARGENTINA: San Martín (1917), including rarities!!

RARE DESTINATION and error in the rate: Registered cover sent from CORONEL SUÁREZ to PALESTINE on 27/AP/1923, franked on back with 27c., with transit mark of Buenos Aires and arrival of Jerusalem 4/JUN. The corresponding postage for a single-rate registered letter to this destination was 24c., by mistake the postal clerk interpreted that the additional 3c. charged to domestic registered letters was also applied to letters sent overseas, resulting in an unnecessary expense for the sender.
