It is ASKING silly money everywhere. But any deck is is worth exactly how much someone will pay for it - no more, no less; there's no Blue Book of tarot - and things are sliding down rather. There's one on ebay at the moment for $103 Canadian - no bids and only 6 hours to run. And there's another in the UK for 82 quid. Let's see if they sell. The only way to tell if people thought they were worth that much. (Both those are complete with the box, though.)
Oh - and one in the UK that sold in April - for 18 quid.
