This piece was my grandmother's who is no longer alive. We pulled out and cleaned it up using a "speedy plate" with washing soda. There seems to be some discoloring and spots on it. There are no markings on the bottom at all. Magnets do not stick to it. I'm just curious if anyone knows its origins, what it might be made of, what it might be worth if anything. Thanks!
I am almost sure it was made to serve meat on , you will notice that the piece has indentations and then a larger "dent" for the dripping's to run into . If it was silver then you would find markings on the bottom of the piece, yours does not have any markings . It is possible you could do a search on eBay and you might find answers to your questions and possibly find some thing simular.
This appears to be a William Rogers Silver Plate "Fenwick" 18" Footed Meat Platter, several of which are listed on various sites for around $30 USD.
There were a staple on many tables from the early 1900s to the 1960s. The center pattern is called the well and tree. Used to drain juices from meats.
Most are plated silver usually marked epns electroplated nickel silver. I had a pewter one I could not give away. They made way too many so there is a huge supply out there and little demand. Yours as a little bling to the edges so you may fetch more. Check the edges and grooves carefully for a marking. Many companies made these. Sometimes maker center of underside. Sometimes the edges.
If I had one was to sell it on ebay, I would take 12 good photos, run it as a buy it now, best offer, starting at $50 and then drop it every few days until you get an offer which may be as low as 4-5 dollars plus shipping. It needs wrapped well so it won't get dented or bent in mailing. Post back how it goes!
I think this is a fish plate and it is not silver. It may be silver plated. It is not valuable.
I found a tray with a very similar pattern but in not so good condition:
