We have ruled out:
1997 december bessatsu.
1997 august, september, and november corocoro comics
This is the very last part.
See this thread? they say in 1998 they reprinted it. The original print was 2000. Then a copy print of another 2000. For each card.
My last question is, this should disclose the amount to be 2,000 copies total of Surfing Pikachu 1997. If there was a reprint it would be 4,000. We are getting closer.
