Simpson Hall Miller and Co. Communion set

This is definitely a church Holy Communion set. The pieces are decorated with clusters of grapes and wheat. The wine pitcher is numbered 2344 on the bottom. The chalices are numbered 1344, but the plate has no number.  All have the Simpson Hall Miller & Co. identifying mark on the bottom. I would appreciate knowing what the value of this set might be. Although it is not pure silver, does the quadruple plating add something to its value?

Good
