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.

“Lion Gardiner, and His Descendants” by Curtis Gardner. It was published in 1890. The cover has some damage (the front cover is barely attached). But the Pages are all intact. The fronts piece contains a handwritten dedication to Chauncey Gardner by the author.

I have a dining set consisting of a large and small buffet, table and china cabinet. I'm wanting to sell it but don't know what a reasonable price would be. Please assist. I also have a hall tree and will upload a photo later.

The other chair matches but, unlike the one pictured, does not have a crack.

I believe these chairs are from the early 1600s. Besides the fact that my grandparents told me that (they brought to the U.S. from Germany, in the 1940s,) the uniforms of the soldiers conform with those used at that time by soldiers from Oldenberg and Hanover.   

The backs of the chairs are  27.5”/ 70 cm high. 

The seat height is 19"/ 48 cm.

I would be greatly appreciative to get some guidance as to their potential value, and the best way(s) to sell them.

I am located in Colorado, USA.

I picked this up off the side of the road and then could use Google lense to find it and it sold at auction for about $4,500 I can no longer find this item online anywhere to use as a reference point for pricing. I would love to get a time period on this and maybe am approximate value.
