American coin silver serving spoon, Jones, Lows & Ball, Boston

This serving spoon is 8 7/8" and in nice condition. (Oops there are a pair of these) The bowl is not dented and the wear is only to the rim not the bowl. It is monogramed "J. Mack". The mark is "Jones, Lows & Ball" in a rectangular cartouche. Ca 1839. The second picture is the other spoon.
