Pair of silverplate English sauce boats- any idea of value?

Here is a pair of 19th century English silverplate sauce boats by Hawksworth Eyre & Co. in Shieffield. They seem to date according to the mark from c.1850-1873. They measure 7" long x 3.5" wide x 5" high. They are in very good condition with no dents or dings and no plate loss. Any idea of value? Thank you for your thoughts.
