Arcadian fine china Newark, NJ Spring Glory pattern set

I have inherited some fine china sets from my deceased parents and am trying to get an idea of the value since from my research it seems varied.  The first is a 40 pc set Valmont China Japan Royal Wheat including a complete service for 8 with dinner plates, cups, saucers, dessert plates, serving platter, salt and pepper shakers, cream and sugar containers, a serving bowl and butter dish all in pristine never used condition that my father gave his mother when he was released from the Army in the early 1960's.

The next set is Arcadian fine china Newark, New York Spring Glory pattern in an unusual setup.  It includes a service for 6 of cups and saucers, dessert bowls, large serving platter, medium serving platter, cream and sugar set, and a covered serving dish.  This belonged to my stepmother and am unsure of its provenance.  I have not really been able to get an idea of its value since it's an unusual setup.  The dishes are also in pristine condition and look to have never been used but I am unsure of this.  Could someone help me with this information? I am including pictures for ease of reference as well.

Excellent
