I have a very nice Norse Pottery Vase that I’m hoping for more information on. It is an amphora style Vase that is approximately 13.5 inches tall. It is marked with the Norse Pottery Mark and the number 1. I had read that the lower the number, the earlier the item. Does anyone know about the numbering on Norse pottery and whether this affects the value? I’m currently estimating the value to be between $200-$600. Any information would be so appreciated.
