Just because the Urd cel appears to be a repro 
doesn't mean that the seller's other AMG cels are 
repros too.  (Actually, the Urd cel is pretty 
cute and is probably worth the buy-it-now price 
even as a repro.)  And I also believe that a lot 
of sellers don't know that their AMG cels may not 
be production cels.  It's sometimes very 
difficult to tell, and the Belldandy cel is a 
tough call, as I have said in an email to person 
with the original question.  (Along the same 
lines, I wouldn't be totally surprised if some of 
the cels in my own collection are repros.)  

Still, I have to wonder why the buy-it-now price 
was a small fraction of what the production cel 
would go for at most dealers or on extended 
auctions on ebay or Yahoo Japan.  It seems a 
little high for a repro but not out of the 
question for someone who values its beauty.  Or 
perhaps the seller just isn't knowledgeable about 
the approximate market value of Belldandy 
production cels of that caliber.  Or perhaps he 
does know its worth and is being kind-hearted to 
some AMG fan.  Who can say?
