I think there is a small difference between 
baseball cards and anime cels. Baseball cards 
they can always print more of the next day, with 
anime production cels the're unique. When they 
are gone, thats it, no more. This is why i feel 
that the cels will always retain their value, and 
the market wont drop ever as severe as bb card 
market. It may fluctuate due to age demographics 
and other perceptions, but not as harshly. I dont 
think a Ken Griffey Jr card is worth the paper 
its printed on. But thats just monetary value. 
It would be nice to pick up a cel for that price 
but i'd have to fend off every one else and end 
up getting the same amount, so its six of one and 
half dozen of another. ^_^x
