RSA 1969-1971 POSTAGE DUE MNH (EXTENDED SET-AFRIKAANS ON IN SOUTH AFRICA

YOU NEED AN ULTRA-VIOLET LIGHT TO DISTINGUISH BETWEEN SWISS PAPER AND HARRISON PAPER. SWISS PAPER SHOWS UP PINK UNDERNEATH AN ULTRA-VIOLET LIGHT WHILE HARRISON PAPER SHOWS UP GREYISH-WHITE. THE SET ON OFFER HERE INCLUDES SACC 57aH AND IS HARRISON PAPER, ALL WITH THE AFRIKAANS ON TOP. NB!!! SACC 58aH (THE 4c VALUE) WITH THE AFRIKAANS ON TOP DOES NOT EXIST. BELOW IS AN EXTRACT OF THE FEEDBACK I GOT FROM A STAMP DEALER: They were only issued in April 1971, probably in a hurry due to a shortage of these 2 values at the time, and were to be replaced by the new designs to be released in March 1972. With less than a year required for use, I doubt the printing quantity was significant, hence their relative scarcity & price. It can therefore be presumed why there was no need to print the 4c in both languages. However, despite the lack of printed evidence, I have been in the trade since 1972 and it has always been common knowledge that this is the case and I can assure you, because these 4c stamps are all quite scarce, I check them every time I get in any. In over 44 years of experience, not a single Afrikaans copy has surfaced but the English version has regularly.
