OldSchool wrote:If it is N•C, then you could try Nathaniel Coleman. His was a silversmith based in Burlington, New Jersey, from around 1790 through to the mid 1830s, and his mark was very similar to the one on your spoons.
There are some examples of his marks on this Roots Web reference to Nathaniel Coleman:

These spoons were made at least a decade before Coleman was born. Another spoon with this mark was offered at auction a while ago, but I had no luck tracking a likely maker working c 1740. I have not decided, from the images I've seen, whether it is N•C or N•G
FYI, I abandoned my Rootsweb pages seven years ago in favor of my own independent site:
