Hi! My name is ***** ***** I would be happy to help with your Gorham spoon.
Thanks for the description and the photos, I know exactly what you have.
This is an authentic vintage reproduction, made by Gorham some time between 1930 and the 1960s, of a well known spoon called The Rochambeau Presentation Spoon which is now part of the permanent collection of the Newport Historical Society museum in Rhode Island.
The original spoon belonged to General Count de Rochambeau. It was part of the huge canteen of silver he took with him on his military campaigns (as one typically did in those days if one was a wealthy aristocratic military officer).
He was one of the French commanders who came to the aid of the colonists during the War for Independence. When in Rhode Island, he became great friends of the Jabez Bowens family of Providence and was their guest on many occasions. As a token of his gratitude for all her hospitality General Rochambeau gave Mrs. Jabez Bowen a large spoon (this size of spoon is known as a "stuffing spoon") from his personal canteen. Bowen descendants treasured the spoon for many years, had it engraved with the inscription you see on the handle, and eventually donated it to the Newport Historical Society.
Your replica by Gorham is a faithful copy in a silver plated nickel alloy: the "EP" flanking the anchor stands for "Electro-Plated". The original, of course, would have been solid coin or sterling silver.
Reproductions of this spoon were made by the Gorham Silver Co. between the mid 1930s and 1960 and they often turn up for sale on the secondary market (auctions and eBay etc) where they typically sell in the range of $30 - $40 particularly if they still have their original felt sleeve and presentation box.
If you saw yours for sale in an antique store it would have a full retail price tag of about $80. This is also the replacement value and what you should insure it for.
I do hope this helps!
