Following some experiments started in 1981, the first series of public telephone cards saw the light in 1988. They were four magnetic cards, with values of 1, 2, 5 and 10 leva, with the same graphics but different colors. The design of these cards continued, with small variations, for a few years; but the first series can be easily recognized by the presence of the control code in the upper right corner, absent in the subsequent series.
Two editions were made, which differ in the “Nr” character that precedes the code. The first run included 22,000 copies of the cards with values of 1 and 2 leva, 23,500 of the 5 leva, and 20,500 of the 10 leva; the second circulation was more limited: 8,000 copies of the values 1 and 2 leva, 6,500 of the 5 leva and 3,500 of the 10 leva.
