The first generation test cards are these SAMPLE cards. These were encoded by telecom for use in early testing from 1987 to 1988. Values were hand written in permanent marker bottom right corner. Values from $2 up to $100 have been seen, but there may have been some higher values also.
This example has been cut before or after testing, but is a genuine example of testing with these cards. The museum would like to acquire an undamaged USED example of the “SAMPLE” test cards
