Wood & Hughes Coin Silver Fork ,"Olive" Pattern

A coin silver dessert fork, 6 an 15/16 inches long, in the "Olive" pattern, marked "Wood & Hughes" incuse and "W [&] H" incuse with the mark that the 4th ed. of Rainwater identifies as being used after 1871. However, since the fork is coin and is not marked sterling, I expect that it was made before 1871, possibly by William Gale, and marketed by Wood & Hughes in NYC later. Engraved "J. I. Crosby" in script. Tines worn unevenly, but still quite usable. Wood & Hughes were in business ca. 1845-1849.
