Thank you for the images, please allow me some time to look these over for you.
I have received your images and thank you for your patience. Blue and white tin glazed earthenware that is made in Holland is called Delft (with an upper case D) it is both the name of a Dutch city and for this type of ceramic ware. Blue and white wares from other countries is referred to as delft-style with a lower case d.
The pieces with RXC marks are actually German porcelain done in a delft-style decoration. Bear in mind, true Delft from Holland is tin glazed earthenware, whereas porcelain is naturally white and made with kaolin and petuntse clays. In other words, 3 of your plates are a different material than the one with the numbers 1658 on it.
The plates with RXC marks were made in Germany from 1896 - 1906 by Rosenthal in their "delft" line. The additional names such as Versailles and Lion D'Or are for the mold shape pattern. The decoration on the plate is transferprinted not hand painted. These each sell for up to $20 per plate.
The plate marked with the numbers 1658 was actually produced in the 20th century. The decoration on the plate is hand painted, not transfer printed. The number series is for inventory cataloging and not a year. The maker initials/mark is LVS which is not from the Royal Factory. On today's market, that plate can sell for up to $40 depending on size.
