Colorful GPT cards which are well known to collectors were introduced in Singapore in 1989, but Tamura cards have been in use since 1985. The first cards were a set of 5 values, $ 2 (160,000 printed), $ 5 (30,000), $ 10 (10,000), $ 20 (10,000), and $ 50 (10,000): they were without notch as typical of cards in that period. Later on, in 1987, larger quantities of cards were reprinted with the same graphics, but they could be easily distinguished by the first ones as this time they are notched.
