Hi & Welcome to JA!

Sorry it took so long for you to get a reply. While I was not able to find this exact pattern either, I was able to find several comparable patterns that give me a very good idea as to what your plates are worth. From my research it seems to me that Montrose may be the pattern name, but that this particular version is a predecessor to a later Montrose pattern that maintains the same form/shape (i.e., the patterned swirls) but changes the decoration slightly to an overglaze blue and pink floral motif that is remiscent, but not identical to the pattern on your plates.

The mark according to my books dates your piece to c. 1900 during a time period when Minton removed the crown from the top of the globe. This is consistent with the pattern. The fact that your plates are blue and white and in a very pleasant pattern that would coordinate with other blue and white plates makes them more desirable than some of your more modern or average Minton pieces. I've seen similar plates with similar patterns and of the same age selling in the $80-100 per plate price range at retail (assuming no cracks, chips or staining or other serious wear). The oval serving tray at retail is in the $125-150 range. Generally, I tell my clients that they should try to get 1/3 to 1/4 of the retail price when selling the objects to dealers or on eBay or Craigs list. In other words for your set of 5 plates plus the oval serving plate, I would probably ask between $125-175 if I wanted to sell them within a reasonable time frame. You might start on the higher end and see if you get any takers. You can always lower the price. If you happen to get lucky enough to find a collector you might be able to get $200-250, maybe $300.

I hope this answers all of your questions. If you are satisfied with your answer, please click the accept bottom so that I can be compensated for my time and use of my paid subscription databases. If you have further questions, please ask.
