I have the secretary and the Dolly Madison dishes. All of the dishes are numbered and I more pictures of the bottom of each dish. The secretary is in excellent condition and I was wondering what to sell these items for. I have other items I will ask about later if you can help with these.
Looks like a provincial porcelain, I am not a great specialist in these things. At least 19th century, may be older. Body colour is not white, rather grey with green tinge. No crack or damage except some imperfectnesses on the rim which more look like a factory defects.
If there is a buyer for it then it is better to do it through eBay/PayPal system unless the buyer has an agent in NZ.
