I'm not quite the person to estimate the value 
of Kenshin cels (seeing that I don't collect 
them or anything..) but I will say that it seems 
that even cels from the more popular series 
these days aren't getting the money that they 
might have a year or two ago. I'm sure this has 
a lot to do with the economy, since a lot of 
people seem to be forced to sell the greater 
part of their collections to finance 
more 'important' things like cars, homes, family 
emergencies, etc. Or, there are just those of us 
who randomly get annoyed or bored with their 
collections and sell some cels to buy new ones, 
or just to make a change.

I know I've taken a hit on a couple cels that 
I've sold recently, but I realized that I'd much 
rather see them go to a good home where they 
will be well cared for than worry about how much 
I pull in for them. The cel market is so fickle 
right now -- for instance, I have a cel listed 
on evil-bay right now that is getting FAR more 
attention than I ever expected. It's a nice cel 
and all, but like I said, I didn't expect the 
interest in it that I'm seeing. ^_^ (not that 
I'm complaining)

Now, I know I didn't directly answer your 
question, just danced about and vented about the 
surrounding issue ^_^ (guess I should be a 
politician?) I'm sure that someone here might 
have an idea about the kenshin cels, so GOOD 
LUCK!
