According to the Customer Service reps I chatted with this morning from our insurance carrier, as long as the precious metals are decorated in some fashion and not plain bars (or "chunks" as they referred to them )that they are covered with our shipping insurance. Whether the silver is in the shape of a coin, rectangle, etc., it can be insured as long as it's not a plain undecorated piece of metal. Let me know if there's anything else I can check for you. Thanks!
