Awesome, thanks for the additional input. I'll set replacement value at $2500.
And special thanks to you, KC. I think this may have been in MsGhopper's family since just after the Civil War. We inherited it recently, along with the Meissen busts, the French tapestry, and some other items. Maybe I'll post some more items later on.
The patina on the bookcase is amazing and yes, irreplaceable. I don't want to think about finding another one.....
