Recently I hired movers and a porcelain plate that belonged to my grandmother was broken. Obviously it is not physically or emotionally replaceable, but to include it in my loss claim I need to prove the value. I’ve found the Mitterteich Bavaria stamp but nothing on the artist or exact plate. Can someone please help me aquire the value? I’ve tried several times to include pictures but the site says even the smallest camera setting is too large for one picture. It is a pair of blue birds on a branch, signed by what appears to be Wilma Knobbs 1986 and has the Mitterteich Bavaria stamp on back center.
I normally never comment on value but in this case the original manufacturer has absolutely nothing to do with any kind of evaluation as the item was obviously (re)decorated by a hobbyist or porcelain decoration student.
As the person was/is not a known artist (e.g. like Mr.. Warhol or such), the insurance company can simply argue that the plate was not in its original sales state *before* it was broken, meaning that the re-decoration itself had already defaced and devalued the original item.
