hello,

These are only my thoughts and will more than 
likely ramble and might not make any sense excpet 
to me, whether a signatuer makes it more or less 
vaulable is a personal judgement call as to if 
the signature is vaulable to YOU, because the 
worth of a cel is personaly enjoyment :)  


I think there are lots of variables, and it could 
affect the costs either way, such as who 
signature it is, someone who's name is synonymous 
with what projects they work on such as Yu 
Watsase, Shinichirô Watanabe,  Rumiko Takahashi 
and Hayao Miyazaki,if they signed the cel,would 
make the cost of buying the cel rise *I think*, 
but an american voice actor or most Japanese 
production staff, would not be as vaulable.
 
Sometimes the signature fills up an empty space 
and if you don't believe that you can match up 
the missing layers later it is a good way to use 
the space.

If your getting the cel signed, I think getting a 
second piece of acetate over the first is a good 
way to protect the cel.

In my case, I only own one signed cel.... 
My cel did cost more than my second cel from the 
same sequence because of the signature,*bought a 
week a part from each other* I don't regret the 
difference in price, and if I did sell one of the 
two, it would be the unsigned one because of my 
sentimental value of being signed by someone I 
worship.
