Many dealers buy cels on the secondary market and 
this affects their list price. Say I was a dealer 
and bought some cels from FY for say $500.00. 
Usual profit margin is 30%? (I'm guessing) so I'd 
list it for around $750-700.00.

Even if  the market moves on FY cels the base 
cost of the cel is $500.00, so I need to recover 
at least that much. The business imperative is 
that otherwise you have suffered a loss.

For collectors the question is different. If 
you've bought something you'd normally try and 
recover what you paid, however, there are other 
big reasons such as another big expensive cel 
which affect your decision. For instance I would 
not hesitate to "take a bath" on a cel (which I 
have more than once) if I really don;t want it 
anymore.

The biggest "bath" I've taken has been about 
$200.00 (received less for a cel which I bought). 
Its feasible for a collector cause we do not make 
a living or earn $ on cels but collect them.

I've found that big prices do not distract 
people. if the character/series is popular 
enough. Enormous price tags in the thousands do 
not matter - also refer Disney cels.....
