UPDATE: I had originally titled and written this thread with the assumption that these later packs contained corrected versions of Japanese Neo Genesis error cards. However I’ve since uncovered a box opening video from all the way back in 2010 which not only includes these newer packs but still pulls the error versions. For reference, see A second Japanese Neo Genesis print run - but why?.
I believe it was @KEI who a few months ago posted a story on Instagram showing a picture of two Japanese Neo Genesis booster packs with different International Article Number (EAN-13) codes. These booster packs both feature a Pichu on the back, and since then I’ve been on the lookout for one. I finally won one at auction earlier today.
This version has a EAN-13 code of 4521329 00794 6 and an ST product certification of “1”:
Japan’s Neo Genesis set had several text-based errors and eventually had a corrected print run, but the corrected cards are much less common than the error versions. I believe the above booster pack to be from this corrected print run. (See Japanese Neo error cards) and Neo Genesis Quilava Error Card? if you’re not sure what these are.)
It’s much more common to find packs with a EAN-13 code of 4935228 98512 8 and an ST product certification of “9”:
Both packs are otherwise identical and completely indistinguishable from the front.
From Wikipedia, EAN-13 codes are formatted in the following way:
- The first 3 digits denote the country of manufacture;
- The next 4 digits denote the manufacturer;
- The next 5 digits denote the product number;
- The final digit is a checksum.
Note that I’ve simplified that a little to make it easier to understand.
Japan has 2 different country code ranges, the old range of 490 to 499 and the new range of 450 to 459. The more common packs have a country code of 493 and a manufacturer code of 5228 whereas the one I picked up today has a country code of 452 and a manufacturer code of 1329. Likewise the more common packs have a product code of 98512 and the corrected pack has a product code of 00794.
Japanese Base Set booster packs used the 493/5228 code:
In fact, all Pokémon releases had the 493/5228 code in Japan up until after Japan’s Neo Discovery set. Here is a Japanese Neo Discovery booster pack with the same code:
The Japanese Neo Genesis set was originally released in December 1999 followed by Neo Discovery in July 2000. The next set to be released in November 2000 was Neo Revelation:
With this set the code had finally changed to 452/1329. The next release in March 2001 was Neo Destiny:
Product codes are sequential, which is great for us because it means we an use Neo Revelation’s product code of 00727 and Neo Destiny’s code of 00819 to quickly see that the corrected Neo Genesis pack’s product code of 00794 falls between the two. With this we now know that the corrected Neo Genesis pack was released between 23rd November 2000 and 9th March 2001.
Earlier I mentioned another difference between the two packs: the ST product certification. The regular Neo Genesis release had an ST code of “9”, but the corrected version has an ST code of “1”. You’ll also notice above that the Base Set pack had an ST of “6”, Neo Discovery and Neo Revelation have an ST of “0” and Neo Destiny has an ST of “1”.
This is really obvious once you know what it is, but it wasn’t until @chok pointed out to me on Discord that these ST values relate to the year of manufacture: 6 in the case of Base Set would be 1996, 9 would be 1999, 0 would be 2000 and 1 would be 2001. Later years prefixed this with the decade number as well to avoid confusion (i.e. Japanese packs released in 2006 have a code of “06” instead of “6”).
With this information we now know that the corrected Japanese Neo Genesis packs were released at some point between 1st January 2001 and 9th March 2001.
How they were released is not known to me at this point - I don’t know if these packs were sold individually, released as part of some other product or released as part of a trade-in for the original error versions. I’d love to see a picture of a corrected booster box, but I can’t imagine one of those popping up any time soon.
What is interesting is that this correction came after the English Neo Genesis set was released in December 2000 (1 year after the original Japanese release) - I wonder if it was the translation process which uncovered these errors in the first place.
