Your spoon is coin silver. (literally made from melted coins, and with a silver content of about 90%). The embossed pattern on the handle is called "Sheaf of Wheat". It was made between 1820, and 1840. (much more likely to be the earlier side of that range). Coin silver spoons with a Sheaf of Wheat are typically (but not always) from New York makers. Sometimes they were imported into the South (mostly by Charleston and Savannah Silversmiths). Sometimes (although not as often) they were made by Silversmiths in the South, who had previous Northern connections.
If you look closely on the back of your spoon, you will probably find worn evidence of a maker's mark.
With a good photo of the mark, I could tell you the spoon's precise origin.
