Despite I’ve already answered this question on the Discord Server some times in the past, I’ll answer it again, but now here (in this thread)
In a nutshell, I found this site by accident. I’m a card researcher (I search information about cards and also edit images via Adobe Photoshop). I remember 2 specific articles that I found while doing researches about e-Reader.
- The first one was e-Reader Serial Code Prefixes. It’s known that e-Cards had IDs (Both in Japan & Occident). This thread basically makes an organized summary of e-Reader IDs Prefixes. Extremely useful thread.
- The second one was Pokémon TCG Picture Dump. I think that’s when I discovered about the “Auction Sample e-Cards”. Very useful thread in my opinion. It was useful for me!!!
Then, I found other 2 articles (articles which convinced me to join here and the Discord Server):
- The first was Sets and Languages: Compilation overview list. Believe it or not, this thread made me finally understand Base Set variants. (Base Set is a mess regarding variants). Thanks @quuador for this amazing thread!!!
- The other was Japanese Unlimited E Series 1 Cards (Base Expansion Pack) … Thread where E1 Unlimited cards are registered. Very useful thread in my opinion.
The rest is history … I joined and here I am … writing about Pokémon Trading Cards during free time … and I really like it!!!
Thanks for everything!!!
