George P. Bent Crown Piano

[mjgrami]

Hi,  I bought an old George P. Bent Crown Piano at an auction a while back.  I'm wondering if anyone can give me an idea as to it's worth.  The woodwork is in pretty good shape.  The keys are of ivory, I believe - almost all are intact - a couple are missing a section or two.  It plays - needs to be tuned.  From the serial number, it was produced around 1898. 

Your help and/or suggestions would be greatly appreciated!  I'd really like to have some general idea as to what it's worth.  Thanks!
