True, it technially SHOULDN'T lower the value. 
But wht many people believe as myth eventully 
omes true...if people think, myth or not, tati 
lowers value...it will ^^;; Collectors are odd in 
some respects...I know a lot of people who don't 
like a ce touched after it's come from 
production. They feel that restoration removes 
the originality of it. After all, those aren't 
the lines we saw on-screen. I can undersand it, 
in a way...i's like having a painting restored. 
It looks prettier, but something in the back of 
your mind keeps saying "But those aren't the 
original artists lines"...it's freaky, in tht we 
like our cels pristine but many can't stand 
having them "touched up". While it gains 
aesthetic value, it loses production value. I 
still cast my vote for having it done on another 
layer...it's a win-win situation ^^
