For those of you who like to have very thorough collections, such as owning all misprints or RH cards of each set), I have some news for you. I'm sure some people are aware of this, but the cards that were printed between Ruby & Sapphire and Power Keepers had a 9 digit or lettered code printed in the bottom left corner.
As far as I know, the codes dont represent anything more significant than perhaps organizational purposes for printing and layout on the sheets.
What I have found by looking at pictures of cards and from some other members, is that there is a certain pattern to the codes.
All codes for an individual Pokemon are identical for the first 6 digits of letters. Only the final 3 differ.
EX Ruby & Sapphire - EX Deoxys (not including EX Team Magma VS Team Aqua)
Common: 3 different codes + 1 RH code = 4 total codes
ex.) ABC, EFG, JKL + XYZ (RH)
Uncommon: 2 different codes + 1 RH code identical to one of the non RH codes = 3 total codes
ex.) ABC, EFG + EFG (RH)
Rare/Holo/UR/SR: 1 code
Ex Emerald/Unseen Forces/Delta Species
Common: 3 different codes + 1 RH code = 4 total codes
ex.) ABC, EFG, JKL + XYZ (RH)
Uncommon: 1 different codes + 1 RH code = 2 total codes
ex.) ABC + EFG (RH)
Rare/Holo/UR/SR: 1 code
EX Legend Maker - EX Power Keepers
1 code regardless of rarity of card.
I would also like to mention that any European language will have the same codes. Japanese cards, however, have completely different codes. I have not yet figured out if 1st edition cards are treated the same as RH in English by having only 1 code.
EDIT: So, I think I figured out Japanese codes. I asked around to see if people could tell me what codes they found on the Japanese Voltorbs from the EX sets and I believe I found a pattern. So far, it seems that each common has up to 4 different codes (like English, including the RH). As for the 1st editions they have identical codes to the unlimited ones. So that means, for any 1 common card, there are 8 different versions; 4 unlimited codes and 4 1/e codes. Hope this is accurate.
Anyway, I started this thread to see if I could get some more information on these codes.
