If you do not know how to find the closed auctions,, come back here and I will tell you how to find them !! That will tell you what people are actually paying for similar items !!
The asking prices or starting prices tell you nothing and do not equate to an items value !!

[b]Porzellanfabrik von Schierholz[/b], from the city of Plaue, Thuringia region, Germany. Shown mark used 1907 until 1962 as far as I can remember. Best hint on value? Closed auctions on eBay.
