Steinway estimate?

Greetings, 
  Not so fast there!  Is it ebony, or burl walnut?  Is the soundboard dead as 
a piece of balsa or still tight and resonant?  keys?  Elephants? verdigris? 
   An estimate is only as good as the amount of information that it is based 
on.  This piano could be worth between $8,000 and $25,000!
