1886-1911 Wilcox Silver Plate Co. Cup

I have a water pitcher with two cups Stamped with Wilcox Silver Plate Co. and 8670 on the bottom of the cups, 8651 on the pitcher. See attached of the one of the cups. This cup need to be repaired and the pitcher seems to have been dropped so it has compression dent at the base but other than that it is just tarnished with age. Any idea of a value for this? Also anyone in New Mexico you could suggest to repair the cup?[/img]
