Judy, the superconductors that are presently in use are all very brittle, hard to work, ceramic type materials. In order to be useful they must be encased in, or deposited on a suitable metal to provide strength and flexibility. Silver has been proven to be very suitable for this and because of silver's inherent low resistance to electric current it makes the task of connections to the super-conducting cable significantly easier. It also has suitable chemical properties. Newer processes that use nickle in a tape rather then a wire have been tried but to date the only process that I am aware of that has been made into a commercial success has involved silver as a significant portion of the wire produced.
It is not surprising that the companies who make the wire would rather not make an issue of this, as they would obviously prefer to keep the price of a critical raw material as low as possible.
