Need help identfying maker on Boston Coin Goblet

[jtischler]

I have a coin silver repousse goblet. It is marked COIN BOSTON and has a styleized "L '" as a makers mark. I would sure love to know who made it. It might be helpful to know that the cup is inscribed on the side with the date 1864, so it is likely the maker was manufacturing in Boston at that time.

Thanks in advance!
