The cards we have been able to get up to now have two different face values, 100 and 1000 units, however they show interesting variants on their backs. The 100 units card has in fact a small square at the beginning of each period, while of the 1000 units card we have both a version with a small hypen, and another one with a round dot. We cannot exclude that the three variants could exist for both values, with six different cards. These cards have been issued by Elcotel inc. company, and we can assume they could be valued over 100 euro each. |
