I respectfully disagree.  The premium is just about right on those.  Reading through active threads, one user says he will never pay more than $750 premium per coin and another user is trying to sell a Silver for over what the market will bear and is asking why the cost in BTC has depreciated from just a few months ago. (captnlolers)  I think the answer lies somewhere in between.  There are definitely tangible benefits to owning a physical coin but what will the market pay for it and if you decide to sell; what will your buyer be willing to pay?  Personally don't think you can go wrong with a brass.
