I saw the copy of FF VII with the black insert sell for over $100 ($102) the other day on ebay. I have that exact copy. For the poster that says if Sony makes FF VII available online the value will plummet I disagree. That is like saying if they reprint Michael Jordan rookie cards the originals will fall in value. In the collectable world the original always retains value because it actually is the original. That is why the black insert FF's are woth more than the green insert ones.
Up to a ceratain point, FFVII has so many copys out that once casual(i use that term lightly here) gamers can get it for $10 on PSN they won't need the PS1 copy, then they will sell it, there are around 15 million copys of FF7 in print, I highly doubt there are half that may dedcated collectors.
