Gorham holloware was marked with date letter until 1885 at which time symbols were used.
Flatware like your spoon was rarely marked with a letter. Therefore, if any letter appeared on flatware is was random.
Your spoon dates 1885 by the Gorham Corporation of Rhode Island. See the photo that follows...
What looks like the number "3" appears where you have what looks like a "2." However the symbol at the top matches perfectly - what looks like a wild boar. The numbers coincide with the weight of the various qualities that were made for each pattern.
My research indicates that your Gorham Sterling spoon has a retail antiques store value of $70-80.
A private seller to a dealer can expect 30-60% of retail value.
