EN Gastly Master Collection List

[Quuador]

Since you mentioned you were only collecting English Gastly cards, I hadn’t mentioned the different codes of the Japanese Flight of Legends set. I was indeed aware of them, but thanks for the heads up nonetheless. A lot of the EX era sets have different codes. Here an overview of which sets are released in which languages, where I also mention which EX-era sets have multiple codes available: Sets and Languages: Compilation overview list.

Here also an Excel with all the different codes in English: Pokemon TCG ex Serial Codes - Google Sheets and Japanese/Korean: Pokemon TCG ex Serial Codes - Japanese - Google Sheets (taken from this thread: Complete List of ex Era Serial Code Numbers - #21 by tonysandlin).

What is it with this particular Gastly/era that warranted there being differing codes on these cards?

The exact purpose of these codes have always been a mystery, and even more so why there are different codes for certain cards. The only thing we know about those codes are, to quote myself from an earlier thread:

@Quuador

For decades the purpose of these codes have been mostly unknown, and still are for the most part. The only thing I know is that the Japanese codes can be used to get HD scans on an old mobile app called Pokémon Hiroba, according to this source. That still doesn’t explain why there are different codes, though. So even after all these years, the reason of the codes is still a mystery.
