Help Unable to identify labeling

[Crispybk]

Hi, I recently dug up my old pokemon cards that I had stored away and many of them are mismatched. I seem to have mostly figured out how to organize them, however I am unsure what these Japanese characters on the cards mean and can’t seem to find info on them. Anyone know what it means or what set it’s from?

Here are some examples:

Most if not all are labeled with the world championship 2009 logo on the back. Any help would be appreciated!

Those are actually part of the World Championship Decks, a product where TPCi basically release the decks of the World champions for each division and maybe a select runner-up. From the looks of it, those cards are from one or many of the decks used at the 2009 Worlds.

Those characters you see are actually the player's signatures on the cards, as an added special feature those decks have. However, that also means none of the cards you find would be legal for Expanded or Standard formats, since these decks are illegal for tournament play regardless of if the sets the cards come from are legal.

Hmm, alright. Fortunately I am mainly interested in selling these cards. However, because they aren’t legal for tournament play does that pretty much make all of the signatured ones worthless?

I wouldn't say worthless, it's true competitive players probably don't have any use for them, but seeing as how 2009 was a while ago maybe some collector would be interested. I couldn't say how much you'd get, but you could definitely get something.
