Brass Letter Opener

Q:         I have a heavy brass letter opener marked “Harlow, Breed & Cooley Wool, 184 Summer St., Boston.” Does it have any value?

A :        Harlow, Breed & Cooley were wool dealers in Boston from about 1912 until about 1926. Advertising letter openers made of brass sell for under $20 to over $100, depending on the design.
