Interesting spoon.
I would guess it dates to 1800, or just prior. You don't see too many spoons made of anything other than pewter or silver. If it had been made as a cheaper alternative by a silversmith, I would expect it to have been made using dies and techniques that also were used to make silver spoons (in other words, it would look like a silver spoon, only made of base metal). It doesn't.
I would guess then, that it was made by a blacksmith or someone else skilled in metal working, but not an experienced silversmith.
