I have 6 porcelain cabinet plates for which I would appreciate an evaluation. Â All 6 are the same pattern and with the same marks on the back and different scenes. Â (2 blue, 2 creme, 2 pink colors) Each one has 4 marks: "Bailey Banks & Biddle Philadelphia", "Dore a Sevres" with the letter N under a crown and the number 68 below, "S.46." in a greenish/grayish oval, and "Chateau des Tuileries". Â None of the painted areas appear to be signed. Â The gilding is worn in some areas, but there are no chips or cracks in the plates at all.
Most of the plates have a raised unglazed spot on the back near the S.46. mark.
I have no experience with what the painted scenes should look like. Â Most of the painting is completely flat, with only a few lines in the clothes or details as raised ridges. Â I don't see any "brush strokes" other than the raised ridges. Â Is this normal or does this mean reproduced?
My obvious question is: are these authentic Sevres?
From what I can gather, the marks may mean that the plate was fired in 1846 and decorated in 1868? Â I know that Bailey Banks & Biddle was a high-end jeweler that did carry Sevres porcelain, but I am unable to resolve why all the marks. Â Were they created specifically for BB&B? Â How does the Tuileries mark fit in? Â Is it normal for there to be a long period before decoration?
This is my first instappraisal posting, so thanks in advance, and please let me know if I'm missing any important information.
