Hello and welcome! My name is Doris.
I have been an antiques collector, dealer and appraiser for over 56 years.
I will be pleased to help you.
You are quite right that Pairpoint was a very well-respected firm.
If you send me a photo of the marks, I can date your cups.
I can tell you also, whether your cups are plated or sterling.
I would also like to see a photo of a cup.
What else would you like to know?
You may need to use the macro function (flower icon) of your camera to get a good clear photo of the marks.
If you cannot get a good photo, then sketch the marks and take a photo of the sketch.
To send photos you may use the "attach file" or "add file" in the blue box link on your reply page or the "paper clip" found in the toolbar you see on your reply page.
Please do not send in ZIP format. The jpg or jpeg format works best.
An explanation of this method can be found here:
If another professional enters our exchanges, feel free to tell them that you are working with me if you wish.
