2 coin silver butter knives, scimitar shape

2 scimitar shaped coin silver butter knives, each with engine turned engraving on the blades, ca. 1850-1870. But the engraving is different on each blade. Unmarked except for the word "COIN" incuse. An unidentified pattern. One engraved ""S.E.H." and the other unegraved. A great pair for fashionable entertaining. Could be used for cheese, etc. as well as butter.
