American coin silver gravy ladle, Newell Harding, Boston

I measure ladles from the front of the bowl to the tip of the handle and this one is over 7". It's hard to determine because it has a pronounced curve in the handle, very graceful. It's in excellent condition. The engraved decoration is crisp and the bowl is good. It is marked N. Harding and "coin". Ca 1860/65.
