Antique Sterling Silver forks and spoons

This silverware was a gift to me from a family friend.  It belonged to his grandmother.  There are six forks, and six spoons.  Each piece is etched on the back of the handle "STERLING T & E.DICKINSON".  The handles have a pretty decorative pattern, and have a monogram "D" on the end of the handle.  Each spoon has a monogram "1900" opposite the "D" on the back of the handle. 

The weight of each piece is as follows:

Forks-  2.31 oz Each

Spoons- 1.59 oz Each

Any idea on how much they are worth?  Your help is GREATLY appreciated.
