Re: silverplate silver tea set medallion hallmark
Congrats ! Nice score on your part. I have been an avid collector of antique silverplate for many decades. I found your mark: According to Dorothy Rainwater, undisputed expert and author on American Silver Manufacturers, this mark is attributed to R.Gleason & Sons of Dorchester Mass.
They were known for their high quality silverplate ware, and were out of business in in 1871. Also, a mention (error perhaps) of this mark belonging to Manhattan Silver Plate Co in 1904. Records show Manhattan was founded in 1872. It is silverplate and a beautiful piece of craftsmanship. Assuming it is in extra good condition (appears so) and that it will polish up beautifully, I would expect that in the correct venue you could ask$100 to $175. If you found a somewhat matching tray (not just any tray) it would enhance it's value perhaps. It could be valued higher due to the special finials, strainer inset, and perfect condition. Polish gently but not often. Silverplate does wear off after time. That is why these are rarely seen in such good condition. Well done !
