hi to everyone

i was on ebay.co.uk few minutes ago and i was wondering why so many people do bid for old bskyb blue card (ident 0961). As far as i know this card is useless cause now it's the ident 0963 mainly in use. but if so many people are interrested in the old blue card (with the yellow house on it) there must be a good and valuable reason

anyone has any clue on this and maybe a link or a key word to give me in order to inquire?

thx in advance
