Insufficiently Paid Mail
In 1966, the centimes method indicating the postage due for international mail was replaced by a "tax fraction" (Vienna Convention) system. Insufficiently paid letters were marked with a "T" and a fraction. The numerator was double the amount shortpaid, and the denominator was the country of origin's international single letter rate. The receiving office multiplied the fraction by its international letter rate to calculate the amount due in the receiving office's currency.
