Here's a Stunning Set of 12 Antique Service Plates by Pirkenhammer. They are approximately 10 and 7/8 in diameter and overall in Good Condition. One has a crack going from the edge to the foot (picture 3). They all have some loss to the gold, mostly not bad.
Most also have dark spots on the heavy gold outside border, a couple have larger, more noticeable areas of this. A couple also have uneveness to the finish of the gold (picture 23).
