Hello Peggy, just a little note. Silver goes through a process called "Toning". If you want to clean silver jewelry or silverware it probably is ok, but with silver coins it takes away the value of the coin. But also I guess it just all depends on the collector. If you like your silver coins to look nice for you that is up to you. But if you plan on selling them in the future I suggest you do not clean them. Just food for thought. Thanks
