Brass Bed

My grandmother had this bed sitting in a backroom of her farm for many years.  Paid $500 to have it refinished 7 years ago.  Bed was damaged by movers.  Caps are dented and there are scratches in the clearcoat which is causing tarnishing.  I am trying to find out the before and after damage values of the bed to report claim to moving company.  Any help would be greatly appreciated.  Thanks!
