Hey Everyone,
After continuing on my google sheet for every English stamped card I have come across some that are enigmas and I need your help. So far, the below are the most difficult cards for me to find data on when, and how they released. Any information on them with sources would be very helpful. This is expert level difficulty, good luck.
Ditto (Pikachu) #63 - Comic Con International Stamp
When and how did it release? (2005 comic con doesn’t make sense to me since delta species released in October and the event was held in July. My best guess so far is the 2006 or 2007 Comic Con I just don’t have proof)
Chimchar #76 - Chicago 07 Stamp
When and how did it release? (Distributor meeting doesn’t make sense since there is already the Piplup card that was held in San Diego and there was only one distributor meeting each year. Plus the design is completely different from the other three distributor meeting cards. My best guess is that they had planned to host it in Chicago, had these made and it was moved to San Diego that year so they just handed them out there?)
Pikachu #49 - Pokemon League Stamp
When and how did it release? (Pokemon Leagues don’t make sense since they were canceled during covid and the last league stamp made before covid hit was the flapple 22 which had to be released in retail. There are reports of it popping up in Australia/New Zealand, Europe, and the US. I also found a graded version by CGC that called it “Pokemon Day”. Maybe they released it for a Pokemon Day in 2023 or 2024 League events? Just like they did with Twin Energy 174 Pokemon League Stamp?)
Any help would be appreciated, feel free to check out the google sheet and let me know of any changes that need to be made!
Thanks.
